i dont have ocd and i can relate to those thoughts. fortunately they dont overwhelm me as i am sure they do you. when i get obsessive thoughts i have a technique i use where i imagine a front and back door in my brain. the thoughts come in the front door and i only attach to them long enough to send them out the back door. sometimes over and over. but i dont pay attention to what they say or how they feel, i just escort them on through.
