The buildup phase of a panic attack is the most important phase, because it is when you can prevent it. If you are under chronic stress, you become worn down and have no reserve left. Anything can push you over the edge. But if you regularly reduce your stress through a combination of cognitive behavioral therapy and mind-body relaxation, you will have enough reserve left to handle life’s surprises.
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.)
Some research shows that people who have close and supportive friendships have a greater ability to fight mental and physical diseases than people who are isolated. The mind can be our worst enemy when feeling anxious and having a supportive network that you can discuss and decompress your deepest worries to could help prevent anxiety from consuming your life. Find trusted friends during times of anxiety that you can open up to and know that they will provide a listening ear and supportive feedback about your experiences.
Once the diagnosis of panic attack is made, however, the person may be surprised that no medicines are prescribed. Before medications are started, the person requires further evaluation by a mental-health professional to check for the presence of other mental-health disorders. These may include anxiety disorders, depression, or panic disorder (a different diagnosis than panic attack).
Your heart beats fast, and your breathing speeds up. Your chest may feel tight, and you might start to sweat. If you've ever felt it, you know that anxiety is just as much a physical state as a mental state. That's because there's a very strong biological chain reaction that occurs when we encounter a stressful event or begin to worry about potential stressors or dangers in the future. Other physical symptoms include sweating, headaches, and insomnia. Psychological symptoms may include feeling restless or irritable, feeling tense, having a feeling of dread, or experiencing ruminative or obsessive thoughts.
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. 
i had my first anxiety on 2017 when i was in the last year in my high school and it lasted a year. the first symptoms i had was less sleep and when i sleep then wake up i would feel like i never had a sleep, another symptom was i had a racing heart beat that when i hear my pulse i would ask my self a lot of questions which would make me panic and make my pulse more faster. for that year i had the anxiety, i had reached a very high level in the anxiety like i used to talk to myself and ask what is happening to me, i used to google my symptoms and google would respond like i had a non-functioning glands and felt hopeless and would be like this forever. i used to cry a lot, but i had this part that made me feel better which was PRAYING. i started praying my 5 prayers everyday and reading Quran. After 2days i would sleep better, my pulse went back to normal and the most thing i missed a lot happiness. Afterwards i learnt how to control my anxiety and stress and whenever i feel some pressure i would do a pro-longed sujood and pray. the reason why posted this was i really feel you guys and when i read your posts, i saw myself in 2017 when i was hopeless so i wanted to tell you guys not to worry and you gonna have your life back and will be happy Insha Allah. just be connected to Allah
