How Anxiety Disorders and Depression Can Increase Suicide Risk When Left Untreated

If you searched for something like anxiety, depression, and suicide risk tonight, take a breath. You are not overreacting, and you are not alone in this moment.

Maybe your chest has been tight for weeks and the sadness is starting to feel heavier than the fear. Maybe you are the parent, partner, or friend who noticed something in someone you love and cannot shake the worry. Either way, the fact that you are here, reading, is already a form of care.

Here is what we want you to know before any research, any numbers, or any clinical explanations. Anxiety and depression are treatable. Even when they show up together, even when they have been quietly building for years, there are real paths forward that lower risk and give you your life back.

We have spent more than three decades sitting with people in this exact place at The Center for Treatment of Anxiety and Mood Disorders. Some arrived barely able to speak. Others came in on behalf of a spouse or an adult child. Almost everyone asked some version of the same question. Is it too late, and is this really as serious as it feels?

Here is something we see almost every week in our clinic. A person walks in believing they have “just” anxiety, or “just” depression, and they minimize the other half of what they are feeling. The truth is that these two conditions rarely travel alone, and when they overlap, the risk picture changes in a real way.

One review looking at mental health conditions occurring together found that suicide risk rates in people with both depression and panic disorder ran around 25 percent, compared with about 16 percent in people with depression alone and roughly 5.2 percent in people with panic disorder alone ⁹. That is not a small jump. The combination does something the individual pieces do not.

Why does that happen? In our experience, depression tends to strip away hope and energy, while anxiety adds a relentless, physical urgency to escape how you feel. Put those two together and you get exhaustion plus pressure, which is a hard place for anyone to sit in for long.

This is why we do not treat anxiety and depression as separate silos when they show up in the same person. A careful evaluation checks for both, screens for panic attacks, trauma symptoms, and obsessive patterns, and then builds one coordinated plan instead of two disconnected ones.

If you have been telling yourself that the sadness is the “real” problem and the worry is just background noise, or the other way around, please hear this gently. Both parts deserve attention, and treating them together is often what turns the corner. You are not being dramatic by asking for help with both at once. You are being accurate.

Depression, when it is left to run its course without help, is one of the most reliable predictors of suicide that researchers have ever measured. That is a hard sentence to read, and we want to sit with it honestly rather than soften it.

A large research review puts the numbers in sharp focus. Compared with people without these diagnoses, people with major depressive disorder had about 7.6 times the suicide risk, while people with dysthymia, a quieter and longer-lasting form of depression, had about 4.1 times the risk ². Those numbers describe risk of death, not just difficult days, and they hold even after researchers account for other conditions and demographic factors.

Read that a second time if you need to. The chronic, low-grade version of depression that so many people write off as “just how I am” still carries roughly four times the risk seen in people without the diagnosis. That is why we take it seriously in evaluations even when someone tells us they have felt this way for as long as they can remember.

What actually happens inside untreated depression that pushes risk that high? In our work with patients, three patterns come up again and again:

• Sleep collapses, so judgment thins out.
• Hopelessness starts to feel like a fact instead of a symptom.
• The ability to imagine a future version of yourself who feels better quietly disappears.

Across the course of severe mood disorders, up to about 15 percent of patients die by suicide, and most of that risk clusters in episodes that were never adequately treated or were interrupted too early ¹². The word that matters in that sentence is adequately. Half a dose of the wrong medication, a few scattered therapy sessions, or a diagnosis made in a rushed primary care visit is not the same as real treatment.

Here is the part that gives us hope after thirty years of doing this work. The same research that documents the risk also shows the flip side. When depression is identified early and treated with evidence-based therapy, thoughtful medication management, and enough continuity to actually change the trajectory, outcomes improve in ways that are measurable, not aspirational ¹¹.

If depression has been sitting in your chest for months, or in someone you love, please do not read the numbers above as a verdict. Read them as a reason to make the call this week instead of next spring. That single step, moving from tolerating it to treating it, is where the risk curve starts to bend.

When people talk about “anxiety,” they often mean one thing. Clinically, we mean a family of conditions that look and feel different from each other, and, importantly, carry different levels of risk.

A recent research review combining results from several studies put hard numbers on this. Compared with the general population, people with any anxiety or stress-related disorder had about 2.9 times the risk of dying by suicide. For panic disorder, the risk was about 3.6 times higher, and for PTSD and other stress-related disorders, it was about 3.1 times higher ⁵. Same broad category, meaningfully different signals.

Panic disorder shows up so strongly in the data partly because of what it does to the nervous system. A panic attack floods you with the physical sensation that something catastrophic is happening right now, even when nothing outside your body has changed. Over months and years, that pattern can wear a person down in a way that quiet worry does not.

PTSD carries its own weight. Intrusive memories, hypervigilance, and the sense that you are never quite safe do not just make daily life harder. They shrink the world. We have watched patients slowly stop driving certain routes, stop answering the phone at certain hours, stop sleeping in the same room as a partner, until the life they have left barely resembles the one they wanted.

Generalized anxiety disorder and obsessive-compulsive disorder deserve their own line here too. Both have been named in the literature as potentially independent contributors to suicidal thinking, especially when they sit alongside a mood disorder ⁸. The chronic, grinding quality of GAD, and the tormenting intrusive thoughts of OCD, can quietly erode a person’s sense that relief is possible.

Why does any of this matter for you or someone you love? Because the label matters. “I have anxiety” is not a diagnosis, it is a starting point. A thorough evaluation looks for the specific pattern, because the treatment for panic disorder is not identical to the treatment for PTSD, and neither one looks quite like care for OCD.

At our practice, that is why the first appointment is usually longer than a typical intake. We are trying to figure out which flavor of anxiety you are actually living with, whether trauma is part of the picture, and how depression fits in. That specificity is what allows the next step, whether it is cognitive behavioral therapy, eye movement desensitization and reprocessing (EMDR) for trauma, exposure work for panic, or thoughtful medication management, to actually reach the thing that is hurting you.

If your anxiety has been dismissed as “just stress” for years, please read those risk numbers as permission, not as a scare. Permission to name what you have accurately, and to ask for care that matches it.

We want to be straight with you about something the research world has been debating for years. Not every study agrees on how much anxiety, on its own, drives suicide risk. That is not a reason to relax. It is a reason to understand the signal more clearly.

One well-known research review found that anxiety on its own had a modest connection with later thoughts of suicide and attempts, but it was not clearly linked with suicide deaths during long follow-up periods ³. Another study of depressed patients concluded that anxiety disorders occurring alongside depression were not, by themselves, independent risk factors for suicide attempts in that group ¹⁰.

Read those findings in isolation and you might feel confused, maybe even relieved. Please do not stop reading there.

So which is it? Both, actually. Anxiety alone, measured broadly, is a softer predictor. Anxiety layered on top of depression is where the risk sharpens into something clinicians take very seriously.

That is why our evaluations are built to catch the overlap rather than sort you into one bucket. If you have depression, we screen carefully for panic, trauma, and generalized worry. If you came in for anxiety, we look just as carefully for the low mood you may have stopped mentioning because you got used to it.

Honest research is not a reason to wait. It is the reason we assess both, and treat both, in the same plan.

Most people do not wake up one morning in crisis. The shift happens slowly, in small changes that get explained away as stress, a rough week, or getting older. Knowing what to actually look for can shorten the distance between suffering and help.

Some signs live inside the person, and some show up on the outside. Both matter.

Pay attention if you or someone you love is experiencing:

• Sleep that has broken down for weeks, whether that means lying awake until 3 a.m. or sleeping through most of the day
• A sense of hopelessness that feels like a fact, phrases like “nothing will ever change” or “they would be better off without me”
• Panic attacks that are getting more frequent or more intense, especially if they come with the thought that you cannot keep living this way
• Withdrawal from people who used to matter, canceled plans, unanswered texts, a partner sleeping in a separate room
• Giving away possessions, tying up loose ends, or writing goodbye-style messages
• A sudden calm after a long stretch of suffering, which sometimes signals a decision has been made rather than a recovery
• Increased alcohol or substance use to quiet the noise
• Any direct or indirect talk about death, dying, or not wanting to wake up

One data point that has stayed with us over the years comes from the National Comorbidity Survey Replication. Over 70 percent of people who reported a lifetime suicide attempt also had at least one anxiety disorder ¹. That is not proof that anxiety causes attempts. It is a reminder that anxiety is often sitting quietly in the room when the worst moments happen, and it deserves to be asked about directly.

When people picture treatment for anxiety and depression, they often imagine one thing. A weekly therapy hour, maybe a prescription, and hope that it adds up to something. Real, risk-lowering care is usually more layered than that, and the layers are what make the difference.

Here is how we tend to build it at our practice, and what the research supports.

1. 1

   The first piece is a comprehensive evaluation that does not stop at the loudest symptom. That means a psychiatrist and clinician looking at mood, anxiety subtypes, trauma history, sleep, substance use, medical contributors, and any current suicidal thinking, in one coordinated conversation. The World Health Organization is direct on this point. Early identification and treatment of mental health conditions is one of the most effective ways to reduce suicide ¹¹.

2. 2

   The second piece is evidence-based psychotherapy matched to what the evaluation actually found. Cognitive behavioral therapy for the thought patterns fueling depression and generalized worry. Exposure work for panic and phobias, so the nervous system learns that the feared outcome does not arrive. EMDR when trauma is driving the picture. These are not interchangeable, and using the right one is part of why treatment works.

3. 3

   The third piece is thoughtful medication management when it is indicated, delivered by a psychiatrist who has time to adjust, listen, and revisit. Research on mood disorders is clear that inadequately treated episodes account for a large share of the risk, so getting the dose, the molecule, and the follow-up right matters more than starting something quickly ¹².

4. 4

   The fourth piece is continuity. Two sessions and a script is not a treatment plan. Real change tends to show up when therapy and psychiatry stay coordinated over enough time to see the pattern shift, and when a higher level of care, like intensive outpatient programming, is available if the weekly rhythm is not enough.

If your last attempt at getting help felt thin or disconnected, that is not evidence that treatment does not work for you. It is evidence that the plan was not built to hold all of you at once.

If you are the one doing the searching because someone you love is struggling, this part is for you. The worry you are carrying right now is a form of love, even when it feels like fear.

Here is what tends to help, based on the families we work with every week. Ask directly. Saying the words “are you thinking about hurting yourself” does not plant the idea, it opens a door that most people are desperate to walk through. Silence is heavier than the question.

Listen longer than feels comfortable. Resist the urge to fix, correct, or reassure too quickly. What your person often needs first is proof that they are not too much for you.

Then, move toward care together. Offer to help schedule the evaluation, sit in the waiting room, drive them home. People in the middle of an anxious, depressive fog often cannot make ten phone calls. They can sometimes make one, if you are next to them.

Watch for the warning signs in the previous section, and take any talk of suicide seriously every single time. If the situation feels immediate, call or text 988 together, or go to the nearest emergency room. You do not need to be certain to act. You only need to be worried enough.

One group we want to speak up for specifically is older adults. The combination of depression and anxiety in later life is often missed, and the cost of missing it is real.

In a study of late-life depression, anxiety occurring alongside depression appeared in about one in six suicide cases and was tied to a higher load of clinical risk factors. Yet clinicians in that same study tended to rate immediate and long-term suicide risk as lower when anxiety was also present ⁴. That gap between what the data showed and what the treating providers perceived is the blind spot we worry about.

If you are caring for an aging parent whose worry has grown quieter and whose mood has flattened, please do not let anyone chalk it up to “getting older.” Ask for a full evaluation that names both the depression and the anxiety, and push for a plan that treats them together. The signs in this group can be softer, and the risk is not.

If any part of this article has felt like it was written for you, or for the person you love, please treat that feeling as information. It is telling you that something has been carried alone for too long.

The next step does not have to be dramatic. It can be a single phone call to schedule a real evaluation, one that looks at anxiety, depression, trauma, and sleep together instead of picking one to treat.

At The Center for Treatment of Anxiety and Mood Disorders, we offer same-day scheduling, in-person visits in Delray Beach, and secure teletherapy for patients across Florida and beyond. Your first appointment does not commit you to anything except being seen clearly by people who do this every day.

You do not need to have the right words ready. You just need to reach out. And if tonight feels heavier than that, please call or text 988 first, then call us in the morning.
