In an anxiety-related disorder, your fear or worry does not go away and can get worse over time. It can influence your life to the extent that it can interfere with daily activities like school, work and/or relationships. Fear, stress, and anxiety are "normal feelings and experiences" but they are completely different than suffering from any of the seven diagnosable disorders plus substance-induced anxiety, obsessive-compulsive disorders, and trauma- or stressor-related disorders.
Medication does not cure anxiety disorders but can help relieve symptoms. Medication for anxiety is prescribed by doctors, such as a psychiatrist or primary care provider. Some states also allow psychologists who have received specialized training to prescribe psychiatric medications. The most common classes of medications used to combat anxiety disorders are anti-anxiety drugs (such as benzodiazepines), antidepressants, and beta-blockers.
Generalized Anxiety Disorder (GAD) is characterized by chronic and exaggerated worry and tension, much more than the typical anxiety that most people experience in their daily lives. People may have trembling, twitching, muscle tension, nausea, irritability, poor concentration, depression, fatigue, headaches, light-headedness, breathlessness or hot flashes.
Repeated and persistent thoughts ("obsessions") that typically cause distress and that an individual attempts to alleviate by repeatedly performing specific actions ("compulsions"). Examples of common obsessions include: fear that failing to do things in a particular way will result in harm to self or others, extreme anxiety about being dirty or contaminated by germs, concern about forgetting to do something important that may result in bad outcomes, or obsessions around exactness or symmetry. Examples of common compulsions include: checking (e.g., that the door is locked or for an error), counting or ordering (e.g., money or household items), and performing a mental action (e.g., praying).
So I can tell you that panic attacks aren't dangerous, but I recognize that this is "easy for me to say". If you're having anxiety attacks, especially if they're a relatively new occurrence for you, you might not be able to believe this right now. That's entirely understandable when you feel that your life is threatened! You don't need to take anything here on faith. Instead, check it all out. Test everything I say against your own experience, as you work your way through this site.
Anxiety attacks can last anywhere between a few moments to 30 or more minutes. It’s also common for subsequent anxiety attacks to follow, causing the overall anxiety attack experience to last much longer as one episode is followed by another. Even though anxiety attacks eventually end, it’s common for the symptoms and after effects of an anxiety attack to linger for hours or even days, depending upon the severity of the attack and the level of stress your body is under.
If you have Panic Disorder, the chances are very high that you have altered your life in some significant way in an effort to prevent or avoid additional panic attacks. It is common, for instance, for people to limit their travel; to restrict their driving (maybe staying within a certain radius from home, or avoiding highways); to avoid large, crowded shopping malls; and in general, to attempt to avoid any activity from which "escape" may be difficult.
Research demonstrates that the most effective treatments for anxiety are behavioral. Such treatments often involve gradually exposing sufferers to the situations they fear. Anxiety therapy may also focus on changing distorted thought patterns that underlie the condition. Drugs may help patients control their anxiety, but they are typically effective only during treatment and do not usually cure the condition. Increasingly, researchers are finding that mindfulness meditation can be a successful technique that helps lessen anxiety.
Anxiety disorders reflect disorders that share a general feature of excessive fear (i.e. emotional response to perceived or real threat) and/or anxiety (i.e. anticipation of future threat) and demonstrate behavioral and functional disturbances as a result. Panic attacks are a feature that can occur in the context of many anxiety disorders and reflect a type of fear response.
While a single panic attack may only last a few minutes, the effects of the experience can leave a lasting imprint. If you have panic disorder, the recurrent panic attacks take an emotional toll. The memory of the intense fear and terror that you felt during the attacks can negatively impact your self-confidence and cause serious disruption to your everyday life. Eventually, this leads to the following panic disorder symptoms:
Specialized coils that targetes deeper brain regions than rTMS. A patient wears a cushioned helmet (similar to the type of helmet worn during an fMRI). The coil used in dTMS was approved by the FDA in 2013 for treating depression but is currently being studied for the treatment of anxiety disorders such as OCD. The procedue is administered for 20 minutes for 4-6 weeks. Patients can resume their daily lives right after each treatment.
Although each anxiety disorder has unique characteristics, most respond well to two types of treatment: psychotherapy, or “talk therapy,” and medications. These treatments can be given alone or in combination. Cognitive behavior therapy (CBT), a type of talk therapy, can help a person learn a different way of thinking, reacting and behaving to help feel less anxious. Medications will not cure anxiety disorders, but can give significant relief from symptoms. The most commonly used medications are anti-anxiety medications (generally prescribed only for a short period of time) and antidepressants. Beta-blockers, used for heart conditions, are sometimes used to control physical symptoms of anxiety.
ACT is a type of CBT that encourages patients to again in positive behaviors even in the presence of negative thoughts and behaviors. The goal is to improve daily functioning despire having the disorder. It is particularly useful for treatment-resistant Generalized Anxiety Disorder and Depression. The length of treatment varies depending on the severity of symptoms.
Social Anxiety Disorder;Fear of social situations in which the person is exposed to unfamiliar people or to possible scrutiny by others. The individual fears that he or she will act in a way (or show anxiety symptoms) that will be embarrassing and humiliating, often times leading to avoidance of social situations and severe distress when participation in social situations can't be avoided. 
Some people with anxiety disorders might benefit from joining a self-help or support group and sharing their problems and achievements with others. Internet chat rooms might also be useful, but any advice received over the internet should be used with caution, as Internet acquaintances have usually never seen each other and what has helped one person is not necessarily what is best for another. You should always check with your doctor before following any treatment advice found on the internet. Talking with a trusted friend or member of the clergy can also provide support, but it is not necessarily a sufficient alternative to care from a doctor or other health professional.
