I replay conversations for hours after they already happened

Someone laughed at something I said and now I can't tell if they thought it was funny or if I embarrassed myself. That was six hours ago and I'm still analyzing the tone of their voice. I do this after every social interaction — texts, calls, quick chats at the store. It's exhausting and I know most people aren't thinking about it anymore. But my brain treats every moment like evidence in a trial. How do you stop the replay loop?
