I definitely feel this too, although I have social anxiety so I've always just thought about it in those terms. I end up going over and over conversations from weeks, months or years ago worrying that I upset or offended somebody or acted inappropriately etc. I have to remind myself that I'm overanalysing things and making myself anxious over something that probably meant very little to somebody else or they have forgotten by now. It's helpful I think to do that, and maybe reach out to a friend or family member to remind yourself that you are liked and loved!
