I age is 19 years and a computer science student. I don't have friends in my childhood and school life now in college life even people talk to me and try to have friendship relationships but I am not able to manage with my friends. 1.i like to be alone. 2. I don't like my friends cracking joke on me 3. If someone says anything to me even I don't like there jokes or anything like this I used to take it seriously and keep on thinking about it. 4. I used to study at night only after 12 am till 3 am because in morning or evening I am not able to focus. 5. At night unwillingly I used to think about the things someone said and used to cry at night in alone. 6. Even if I try to talk to people after sometime I used to tell lie to them and sits alone. 7. I am too much sleeplessness at night. But feel to sleepy in afternoon even after waking in morning at 10 am. 8. Having headache problem also. I feel like my main problem is study and marks. Because I was a below average student in 11 and 12 but now in college my grades have improved so much in 1st semester. Now in 2nd semester I am having these problems. For example. Yesterday my one of the friend said that my brother is a physics teacher still I am not getting good marks in physics whereas she compared me with one girl who had got full marks in physics saying that his brother is not a physics teacher then also she gets full marks. Actually he was cracking joke but I felt so bad that whole day I had cried thinking of it. Please tell me some solutions for these problems so that I can focus on my studies. Is these are symptoms of anxiety disorder.
