I hate that im always in my head and replaying interactions. Whenever I go to an important meeting (job) and speak I replay the things that I said in my head and get embarrassed thinking about how dumb I must have sounded. This even applies to casual conversations with people I'm not very close to.

Another part of it is constantly thinking about the  problems in my relationship. Like every relationship we have our own problems particularly about communication and mismatch of sex drives. I'll keep thinking about them to the point where I get exhausted and keep bringing it up, which doesn't help either of us. Any advice on how to combat this?
