Not everyone understands is that someone with an anxiety disorder cannot "just let things go". This makes the struggle with an anxiety disorder even harder, and may prevent one from looking for help. However, it is very important to talk about these anxieties with someone and preferably find a health care professional as soon as you experience these symptoms. Anxiety should be considered as severe as a physical disease; however, most people in society do not appreciate the severity of this disorder. Some people may consider anxiety a fault or a weakness; however, it may help if people realize that many research studies have demonstrated biological explanations for (some of) the symptoms observed in anxiety disorders. Brain scans have demonstrated brain abnormalities in certain anxiety disorders, and also altered brain functioning has been demonstrated for individuals with anxiety disorders. Furthermore, there is some evidence that anxiety disorders might be linked to chemical imbalances in the brain.

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.
There are dozens of drugs that can be prescribed to treat anxiety. Since each person responds to medication differently, there's no one drug that works perfectly for everyone. You may have to work a little with a psychiatrist to find the right medication, or the right combination of medicines, that’s most beneficial to you. The drugs that are used to treat anxiety over a long period of time are antidepressants, which affect serotonin, norepinephrine, and other neurotransmitters in the brain.

This may sound counter-intuitive but trying to accept one's emotional experience can be very helpful during panic attacks. Remind yourself that anxiety is like a wave, what goes up must come down. Fighting against the experience engages the "fear of fear" cycle that can make you feel even worse. If you notice panic symptoms creeping up, label your experience and you remind yourself, "I will be okay. This will pass in time." Accepting your experience, rather than fighting against it, will likely help your panic symptoms reduce more quickly and will feel easier along the way.

Exposure therapy has been around for a long time. It involves exposing the patient in a safe and controlled environment to physical sensations they experience during a panic attack much the same way you‘d expose in small increments a person with a fear of trains or puppies or snakes to the things that scares them. With panic disorder, there’s often a heightened sensitivity to ordinary physical sensations such as racing heart, stomach ache or feeling faint. In exposure therapy, the therapist will ask you to mimic activities—like running around or doing jumping jacks or holding your breath—to cause panic symptoms. The idea is that by repeating the things that may trigger a panic attack those triggers will eventually lose their power.
Some research suggests that your body's natural fight-or-flight response to danger is involved in panic attacks. For example, if a grizzly bear came after you, your body would react instinctively. Your heart rate and breathing would speed up as your body prepared for a life-threatening situation. Many of the same reactions occur in a panic attack. But it's unknown why a panic attack occurs when there's no obvious danger present.
People with generalized anxiety disorder (GAD) display excessive anxiety or worry, most days for at least 6 months, about a number of things such as personal health, work, social interactions, and everyday routine life circumstances. The fear and anxiety can cause significant problems in areas of their life, such as social interactions, school, and work.
