Obsessive Compulsive Disorder (OCD) Support Group
Obsessive-compulsive disorder (OCD) is a psychiatric disorder, more specifically, an anxiety disorder. OCD is manifested in a variety of forms, but is most commonly characterized by a subject's obsessive (repetitive, distressing, intrusive) thoughts and related compulsions (tasks or rituals) which attempt to neutralize the obsessions.

No one suspected anything when I was kid. I myself didn't even understand what I was feeling and why.
But now people do notice that I seem to be a bit more aloof and neurotic at times. The people close to me notice that I tend to isolate when I'm having a hard time.
Why don't you feel comfortable being open about your condition? It's helpful to be able to open up to somebody you can trust.
