I had broke up wid a girl 2 years ago but still I m thinking about her every time evn when I do not want to think about. Whenever I tried to do something or travelling or do anything inside my mind something continuously goes on. A regular thinking or thoughts inside will goes on. It pains my head evrytym and make me upset and irritated. I want to forget my past completely and also want to keep my mind thoughts free and Tell me what to do.
