This has been posted to two other groups as well in hopes of getting some answers. I'm a 21 year old male with ADHD and hypochondriasis which causes anxiety and depression occassionally. I'm currently taking ritalin and Xanax, only I abruptly stopped the ritalin about a week ago. Here's the problems I'm having. About 2 days after stopping the ritalin I've found that I cannot concentrate on anything. I'm constantly distracted by anything around me and also by fears of losing my mind and dying. I'm not forgetting much in the way of memory. The exact opposite actually, I remember things I hardly would ever remember. Small, trivial things. I find that I can now hold my concentration if I work really hard at doing so, but I'm not sure how much longer I can keep this up for. My doctor has me going to a neurologist on Wednesday, but I'm really getting freaked out here. They say the chances of it being AD are non-existent because I'm not old enough. They also say the chances of it being CJD or Huntington's are extremely small because the conditions are so rare in people my age that they've never seen a case in their entire career. They think it may be due to anxiety and hypochondriasis along with withdrawl from the ritalin. Has anyone on here ever dealt with this or have you known someone who has dealt with this without it being a fatal, incurable condition? It's just scaring the daylights out of me to think that I could lose my mind at only 21 years of age and that it will eventually kill me. I know I'm saved and going to heaven when I die, but the thought of the process of getting there is just scaring me half to death. Anything you can tell me would be helpful.
