Just Remember OCD is a Mental Bully
If your flying in a Plane and the Plane says you are 20,000 ft high but you looked outside and you could see the ground , what would you believe?
You are not your thoughts
Say your mind is a Pool and thoughts are Balls , A thought pop up and you push it down with Compulsion and Avoidance , it will pop back up and add another thought until your mind pool will be filled with balls/thoughts
