I posted something similar in another anxiety help sub this morning and didn't get any responses, but I was wondering if any other anxiety sufferers had any tips? Does anyone know how to stop replaying memories or situations that you consider "bad" or embarrassing? 

Replaying situations that gave me anxiety in the past or situations where I did something that I consider to be embarrassing to me have a tendency to get stuck in my brain. I harp on it all the time and it usually keeps me up at night. Sometimes I even cause myself to get stomachaches over them. Mainly was just wondering if anyone had any tips on letting things go and relaxing more. 

I have a therapist and I tell her about my anxiety and even harping on issues or worrying about other things but this is still a major problem for me.
