I am 24 year old ocdian suffering from ocd from past 10 years though a bit of small to moderate symptoms were present earlier also but they were not as intense as one's life would stop. I was on paxidep cr 62.5 mg for a long time and on oleanz 1.25 mg for 3 months last year in april but they were weight gaining medicine so my doctor prescribed topiramate 25-50 mg .I took it for 14 days and left oleanz as my wt was about 95 kg. I don't know what happened my nature of thoughts completely changed from then. My thoughts had started coming in a slow manner and they were resistant to any therapy I would practice. Also thoughts of guilt and compulsion which had stopped coming long back restarted again. I took paxidep for 5 more months along with buspin 15 mg for few months. But there was hardly any change I noticed in my condition. I realized that the medicines are hardly having any effect on me. So I stopped the medicines for about 50 days and I saw no change in my symptoms after withdrawal also. My doctor was not understanding my situation So I changed the doctor and they changed my medicines and even then my thoughts slowed down much more. Now when I am studying anything l learn is looking same as anything I don't remember. It's almost become impossible to study. My other concern is that my anxiety has fallen down rapidly after that topiramate incident. So What exactly has happened?
