Persistent and excessive fear of a specific object or situation, such as flying, heights, animals, toilets, or seeing blood. Fear is cued by the presence or anticipation of the object/situation and exposure to the phobic stimulus results in an immediate fear response or panic attack. The fear is disproportionate to the actual danger posed by the object or situation. Commonly, adults with specific phobias will recognize that their fear is excessive or unreasonable.
A panic attack is an abrupt surge of intense fear or discomfort that reaches a peak within minutes, and during which time a variety of psychological and physical symptoms occur. These symptoms include rapid heart rate, sweating, shaking, shortness of breath, hot flashes, and lightheadedness—as well as a sense of impending doom, chills, nausea, abdominal pain, chest pain, headache, and numbness or tingling.
Primarily, it is important to stay calm, patient, and understanding. Help your friend wait out the panic attack by encouraging them to take deep breaths in for four seconds and out for four seconds. Stay with them and assure them that this attack is only temporary and they will get through it. You can also remind them that they can leave the environment they are in if they would feel more comfortable elsewhere and try to engage them in light-hearted conversation.
Many people don't know that their disorder is real and highly responsive to treatment. Some are afraid or embarrassed to tell anyone, including their doctors and loved ones, about what they experience for fear of being considered a hypochondriac. Instead they suffer in silence, distancing themselves from friends, family, and others who could be helpful or supportive.
Everyone here has issues, but what happens when you’re blue as hell and CANNOT figure out the source of the problem? There is no quote, no book, no video, no saying or phrase, no motto, which is helping me right now. I feel like absolute total HELL. And I damned well know it’s not going to last, and that it’s probably a result of thinking too hard, too long, too deeply. Anyway, thank you all for sharing your pain with strangers. It shows that you’re way stronger than you think.
About 12% of people are affected by an anxiety disorder in a given year and between 5-30% are affected at some point in their life.[49][50] They occur about twice as often in women than they do in men, and generally begin before the age of 25.[10][49] The most common are specific phobia which affects nearly 12% and social anxiety disorder which affects 10% at some point in their life. They affect those between the ages of 15 and 35 the most and become less common after the age of 55. Rates appear to be higher in the United States and Europe.[49]
Panic attacks can happen during the day or night. Some people have one panic attack then don't ever experience another, or you might find that you have them regularly, or several in a short space of time. You might notice that particular places, situations or activities seem to trigger panic attacks. For example, they might happen before a stressful appointment.

Expected panic attacks are those which occur when you are exposed to one of your triggers. For example, if you have a fear of flying you may have a panic attack when you board a plane. Expected panic attacks are again broken down into two categories: situationally bound (cued) in which a person is anticipating exposure to a particular trigger (as with our flying example), or situationally predisposed, in which a panic attack does not always occur when exposed to the feared situation.
We have all felt anxiety—the nervousness before a date, test, competition, presentation—but what exactly is it? Anxiety is our body's way of preparing to face a challenge. Our heart pumps more blood and oxygen so we are ready for action. We are alert and perform physical and emotional tasks more efficiently. (See also Test Anxiety for tips on dealing with tests.)
Obsessive-Compulsive Disorder (OCD) is characterized by uncontrollable anxious thoughts or behaviors. Individuals with OCD are plagued by persistent, unwelcome thoughts and images or by the urgent need to engage in certain rituals. Some OCD sufferers may only have obsessive thoughts without the related rituals. The disturbing thoughts or images (e.g., fear of germs) are called obsessions, and the rituals performed to try to get rid of them (e.g., hand washing) are called compulsions. For example, people who are obsessed with germs may wash their hands excessively. The individual is not happy to be performing the ritual behaviors but finds this to be the only way to get temporary relief from the obsessive thought.
Says Clyman: "You might start to consider your emotions as changing experiences that are always fluctuating. When we feel distressed, it can seem like the distress is going to go on and on forever until we emotionally combust. But instead, emotions act more like a wave, at times increasing and becoming more intense. But inevitably they'll reach a plateau, subsiding and finally passing."
In the central nervous system (CNS), the major mediators of the symptoms of anxiety disorders appear to be norepinephrine, serotonin, dopamine, and gamma-aminobutyric acid (GABA). Other neurotransmitters and peptides, such as corticotropin-releasing factor, may be involved. Peripherally, the autonomic nervous system, especially the sympathetic nervous system, mediates many of the symptoms. Increased flow in the right parahippocampal region and reduced serotonin type 1A receptor binding in the anterior and posterior cingulate and raphe of patients are the diagnostic factors for prevalence of anxiety disorder.
Prevention is more effective than treatment for panic attacks. Prevention involves stress management methods such as meditation and mindfulness to reduce your stress so that it doesn’t accumulate and eventually erupt into a panic attack. Prevention is not about stopping a panic attack just before it happens. The best you can do just before a panic attack is manage it.
Although beta-blockers are most often used to treat high blood pressure, they can also be used to help relieve the physical symptoms of anxiety, such as rapid heartbeat, shaking, trembling, and blushing. These medications, when taken for a short period of time, can help people keep physical symptoms under control. They can also be used “as needed” to reduce acute anxiety, including as a preventive intervention for some predictable forms of performance anxieties.
