We all slip up from time to time. It's part of being human. Be gentle with yourself you are worth it.

I'm sorry about the thoughts. I truly understand how they get in there and it's like a hamster on a wheel over and over. I don't know if it will help you but when my thoughts are like that I focus on a sound like EEEEEEEEEEEEEEEEE. It's annoying but if I focus on it enough the sound drowns out the thoughts.
