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.
Why do I feel enraged by my neighbor? Cuz he looks like a jerk. Why do I think he's a jerk? Because he looks at me like I'm this and that.
You get the idea. Then you will realize if it is actually him or is it a past experience or some attributes that are not at all real but me just wanting to release my anger/hurt onto someone.
Try it. It helps to demystify a lot of obsessive thoughts.
