How do you stop replaying conversations?

Hi

We had my daughter's birthday party yesterday. Id been super anxious about it and by the time we got home I was exhausted. Small talk with parents, 15 excited 6 year olds, soft play with no air con....

I went to bed early cos I was so tired but 3 hours later I was still awake replaying all the conversations id had and analysing everything. 

Has anyone found a way to stop doing it?
