not related to my previous post but since I'm here, I figured I'd mention this because it bothers me as well.

I will often wake up feeling guilty or ashamed that I've done something wrong or acted inappropriately or that I did something to be embarrassed about the previous night.

Normally, I have some social issues where I'll always play over in my head and social interactions and will often think I've done something stupid where people will think less of me - I'm trying to deal with those issue but often the feelings in the morning cannot possibly be related to anything that I've done because I will have done nothing the previous day/night.

I would often feel that way when I'd drink too much and then wake up mad at myself that I drank and concerned about how I might have acted around people but I've largely giving up drinking (for those specific reasons and because if I kept drinking, I'd probably be dead) and I'll still wake up feeling like I did something embarrassing.
