its over six months now when i got the first anxiety attack or i think it was an anxiety attack. The thing is at that point of time, i had failed my exams and was preparing for the re-tests, most of my friends had gotten through in the first attempt and were enjoying vacations, it was totally eating me from inside that i was the only guy from our group studying and i think that triggered the anxiety off. I started repeating sentences i was studying over and over again even after i knew them well, it was getting really tough to study because everytime i thought of going ahead i went right back to repeating those sentences just to see if i'd not forgotten them, it still happens regularly and not just while studying, but even on a normal course i just pick up sentences and i start repeating and visualizing as if i din't understand easily what the sentence meant even if the sentence was really simple, like i may just take any random sentence from what i'm writing here and start repeating. Most of the times after great struggle i just manage to get over it and at other times it'll take me more time, sometimes it just wont stop until i've sapped myself of all emotional energy. the same also happens with numbers. also when this happens i feel uncomfortable at the jaw, heart beat increases and it feels really pathetic. Please tell me what this is guys and pray for me.
