I've noticed that I feel a large amount of guilt right after I talk to someone. It usually happens after a casual conversation or just an exchange of greetings with a neighbor or something like that. Its like I feel like I let them down because I wasn't friendly enough or talkative enough with this person and displayed limited social graces. I think it has much to due with the fact that I'm so depressed and anxious. Have other people experienced this too? How do you deal with it?
