I started using marijuana because my OCD got so depressing I had trouble being happy ever I have had many OCDs I had ROCD, HOCD (definately the worst one to ever get), I have an obsession with patterns everything has to be symmetrical, and i also have the irrational fear that I am going to hell, or that I will kill my family when I grow up. I have severe OCD and was diagnosed when I was 7. I used marijuana as an escape when I had HOCD because I would beome really depressed for lond periods of time. I think it actually helped me alot but when I'm not high it's definately alot worse than it was when I was first diagnosed.
