12 Signs You May Have an Anxiety Disorder

Sept. 19, 2013— -- intro: Everyone gets nervous or anxious from time to time—when speaking in public, for instance, or when going through financial difficulty. For some people, however, anxiety becomes so frequent, or so forceful, that it begins to take over their lives.

How can you tell if your everyday anxiety has crossed the line into a disorder? It's not easy. Anxiety comes in many different forms—such as panic attacks, phobia, and social anxiety—and the distinction between an official diagnosis and "normal" anxiety isn't always clear.

Here's a start: If you experience any of the following symptoms on a regular basis, you may want to talk with your doctor.

Secrets to a Healthy, Stress-Free Family

In the case of GAD, it means having persistent anxious thoughts on most days of the week, for six months. Also, the anxiety must be so bad that it interferes with daily life and is accompanied by noticeable symptoms, such as fatigue.

"The distinction between an anxiety disorder and just having normal anxiety is whether your emotions are causing a lot of suffering and dysfunction," says Sally Winston, PsyD, co-director of the Anxiety and Stress Disorder Institute of Maryland in Towson.

And, of course, it's not unusual to toss and turn with anticipation on the night before a big speech or job interview.

But if you chronically find yourself lying awake, worried or agitated—about specific problems (like money), or nothing in particular—it might be a sign of an anxiety disorder. By some estimates, fully half of all people with GAD experience sleep problems.

Another tip-off that anxiety might be involved? You wake up feeling wired, your mind is racing, and you're unable to calm yourself down.

If the fear becomes overwhelming, disruptive, and way out of proportion to the actual risk involved, it's a telltale sign of phobia, a type of anxiety disorder.

Although phobias can be crippling, they're not obvious at all times. In fact, they may not surface until you confront a specific situation and discover you're incapable of overcoming your fear.

"A person who's afraid of snakes can go for years without having a problem," Winston says. "But then suddenly their kid wants to go camping, and they realize they need treatment."

Stress-Relief Tips from Around the World

This symptom can be so persistent and pervasive that people who have lived with it for a long time may stop noticing it after a while.

Regular exercise can help keep muscle tension under control, but the tension may flare up if an injury or other unforeseen event disrupts a person's workout habits, Winston says. "Suddenly they're a wreck, because they can't handle their anxiety in that way and now they're incredibly restless and irritable."

quicklist: 5category: Signs You May Have an Anxiety Disordertitle: Chronic indigestionurl: text: Anxiety may start in the mind, but it often manifests itself in the body through physical symptoms, like chronic digestive problems. Irritable bowel syndrome (IBS), a condition characterized by stomachaches, cramping, bloating, gas, constipation, and/or diarrhea, "is basically an anxiety in the digestive tract," Winston says.

IBS isn't always related to anxiety, but the two often occur together and can make each other worse. The gut is very sensitive to psychological stress—and, vice versa, the physical and social discomfort of chronic digestive problems can make a person feel more anxious.

19 Natural Remedies for Anxiety

But if the fear is so strong that no amount of coaching or practice will alleviate it, or if you spend a lot of time thinking and worrying about it, you may have a form of social anxiety disorder (also known as social phobia).

People with social anxiety tend to worry for days or weeks leading up to a particular event or situation. And if they do manage to go through with it, they tend to be deeply uncomfortable and may dwell on it for a long time afterward, wondering how they were judged.

In most cases, the anxiety is provoked by everyday situations such as making one-on-one conversation at a party, or eating and drinking in front of even a small number of people.

In these situations, people with social anxiety disorder tend to feel like all eyes are on them, and they often experience blushing, trembling, nausea, profuse sweating, or difficulty talking. These symptoms can be so disruptive that they make it hard to meet new people, maintain relationships, and advance at work or in school.

Not everyone who has a panic attack has an anxiety disorder, but people who experience them repeatedly may be diagnosed with panic disorder. People with panic disorder live in fear about when, where, and why their next attack might happen, and they tend to avoid places where attacks have occurred in the past.

quicklist: 9category: Signs You May Have an Anxiety Disordertitle: Flashbacksurl: text: Reliving a disturbing or traumatic event—a violent encounter, the sudden death of a loved one—is a hallmark of post-traumatic stress disorder (PTSD), which shares some features with anxiety disorders. (Until very recently, in fact, PTSD was seen as a type of anxiety disorder rather than a stand-alone condition.)

But flashbacks may occur with other types of anxiety as well. Some research, including a 2006 study in the Journal of Anxiety Disorders, suggests that some people with social anxiety have PTSD-like flashbacks of experiences that might not seem obviously traumatic, such as being publicly ridiculed. These people may even avoid reminders of the experience—another symptom reminiscent of PTSD.

"If you are constantly judging yourself or you have a lot of anticipatory anxiety about making mistakes or falling short of your standards, then you probably have an anxiety disorder."

Perfectionism is especially common in obsessive-compulsive disorder (OCD), which, like PTSD, has long been viewed as an anxiety disorder. "OCD can happen subtly, like in the case of somebody who can't get out of the house for three hours because their makeup has to be absolutely just right and they have to keep starting over," Winston says.

quicklist: 11category: Signs You May Have an Anxiety Disordertitle: Compulsive behaviorsurl: text: In order to be diagnosed with obsessive-compulsive disorder, a person's obsessiveness and intrusive thoughts must be accompanied by compulsive behavior, whether it's mental (telling yourself It'll be all right over and over again) or physical (hand-washing, straightening items).

Obsessive thinking and compulsive behavior become a full-blown disorder when the need to complete the behaviors—also known as "rituals"—begins to drive your life, Winston says. "If you like your radio at volume level 3, for example, and it breaks and gets stuck on 4, would you be in a total panic until you could get it fixed?"

quicklist: 12category: Signs You May Have an Anxiety Disordertitle: Self-doubturl: text: Persistent self-doubt and second-guessing is a common feature of anxiety disorders, including generalized anxiety disorder and OCD. In some cases, the doubt may revolve around a question that's central to a person's identity, like "What if I'm gay?" or "Do I love my husband as much as he loves me?"

In OCD, Winston says, these "doubt attacks" are especially common when a question is unanswerable. People with OCD "think, 'If only I would know 100% for sure whether I was gay or straight, either one would be fine,' but they have this intolerance for uncertainty that turns the question into an obsession," she says.
