The above is right, you're not psycho, you're not even describing OCD. You do sound very troubled right now, and I think therapy is a really good idea. Don't get caught up in labels -- just work on what's bugging you. Good luck.
First thing I want you to KNOW, UNDERSTAND and BELIEVE is that you are NOT alone with these kinds of thoughts and feelings!
The second thing I want you to KNOW is that there IS HELP out there for you! Help that will make these thoughts, feelings and urges go away!!!!
You have shown us how brave, strong and intelligent you are by reaching out to us for help. The best help we can give you on this forum is to advise you to print out this post and give it to your parents! They probably have no idea how badly you are hurting, how scared you are, how badly you WANT help to stop feeling this way. Give them this post and let them get you the help you need..........they love you.
You are not "psycho" and nobody is going to put you anywhere, Toots! You need some therapy and possibly some medications and those tools will get your thoughts and feelings "normal" again.
PLEASE print this out and give it to your parents as soon as possible.
If you need to talk, we are always here.
You were strong enough to reach out to us, use that strength to reach out to your parents!
We care.
