Thank you so much for your post and redirection to a different forum. I really appreciate your advice!
I think that stress or anxiety is more likely to be causing you to forget things as (say) compared to ADHD. A lot of your other symptoms are definitely anxiety related. Try googleing "Generalized anxiety disorder" and see if any of that sounds like what you have got going on. I think you should post to another forum - like anxiety, to get their opinion.
If you have never had these kind of problems before, it may be that being away from the comfortable surroundings of home- plus the challenges of your first year in college has triggered this. At any rate, it is something that you want to deal with. It may be that a lot of these problems will fade with summer. But that could depend on how and where you spend your summer. Exercise can be a great coping mechanism. Combine that with a good self defense class and you should sleep better at night.
So ya, there is something kind of wrong with you - and you know it, or you wouldn't haven't taken the time to write such a long post (excellent writing, by the way). Fortunately, it is fixable. It might even go away by itself (if you never had the problem before), but I would deal with it. Anyway, do post on another forum, I think they can help. Good Luck to you!!
