Since the last 3 or 4 months I'm having a lot of trouble. I love phys, math and chem. I love them so that even when I go to bed to sleep my mind can’t stop thinking about them. But as I said before since the last 3 months, I can’t understand anything. When my teacher teaches me something I think about that too much and end up getting confused. Stupid and meaningless questions constantly come into my mind. Yesterday, I was thinking what do the numbers mean? If I read something new, I read it at least for ten times and still feel unsatisfied. As for the things I already know I write them again and again and again until I get frustrated. I’m tired of it. These things are directly affecting my performance. I take a lot of times to solve questions. I discussed it with one of my teachers and he told me to see a psychiatrist. The problem is due to some reasons I don’t want to see one. Is there anyway to stop it or even reduce it. I don’t want to stop studying these subjects. I just want this thing to stop.
