I can't think clearly any thing. I have trouble in studying. I can't focused my mind in study. I feel uncomfortable when I see face of any person. I think that how he is talking or watching. I create an image of inner structure of body. When I see any word in my textbook I become very uncomfortable and think that what is that. How that become a word. Wahat is meaning of that one. I feel that l have isolated from world. I can't talk normally with any one. Some thing comes in my mind and locked it. I feel l hanging like of a mobile phone. My mind become too heavily. I irritated again and again. I can't think any thing clearly. So many unwanted  thoughts come in my mind. I have allergy with clofranil. I have took so many medicine from various doctos.
