Alright this has happened so much but I've never spoken about it. A lot of times when I go out and socialise (especially if I've been drinking) I'll  talk and have fun and it's all good but then I get home and all of a sudden I am intensely embarrassed and disgusted with myself over everything I said or did and I sometimes even turn off my phone or just ignore everyone because I'm too embarrassed to face them even though nothing particularly bad happened and I left on good with them. Maybe this is just social anxiety
