I relapsed on one of my major compulsions last night. I just woke up and oh man do I feel guilt and regret. I feel the need to talk to my parents and confess how everything happened. Is this a compulsion? Or is this me genuinely confessing?

You can always “spoil” compulsions after the fact! For example, if you engage in excessive hand washing, you can touch something “contaminated” afterwards. If you do a mental compulsion, you can spoil it by agreeing with the original intrusive thought. Instead of confessing, spoil your compulsion and move on! You can do it!

you are the only person who knows the answer to that
