Quieting obsessions: Many young kids are afraid of monsters. We know it's pointless to try to convince them that monsters exist only in their imaginations. In your case, it's like you've got a child always next to you living in perpetual fear that something is (or will be) wrong with you. A psychologist specializing the treatment of obsessions and compulsions can teach you how to quiet this child, so to speak.
