I know how you feel with the OCD and the obsessive, scary thoughts. I am 27 and I was in the hospital for 4 days in December of '05. I stopped eating and was extremely depressed and that is why my mom pretty much made me go in. I will be praying for you.
Remember, even when it seems dark and hopeless, God is there. The hardest thing to do is to not let your obsessions impact your beliefs.
