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.
Just try to draw a line under it, let it go and moving forward, to help you, maybe write stuff down. I know it sounds silly but when you go out, take a notebook with you and every half an hour pop into the loo and write down something like 10pm - still havent cheated! 10.30pm - still havent cheated! Its simple but it might help you..
Good luck and try to start trusting your own judgement a little bit more. You would KNOW if you cheated on your BF if you care about him!!!
