Every time that I have a heavy nights drinking,I get really depressed and worried for the next few days. Just this past weeekend I had a work night out. Everybody from the company was there,which is a few hundred people.

Drink was flowing and my memory of the night is hazy to say the least. I ended up talking with this girl from work,and eventually we went back to a house party.Nothing happened,not for lack of effort on my part,but now im ashamed because I have a girlfriend and she has a boyfriend.Back at this party,some guy accused us of cheating on our partners,and im now ashamed and worried incase this rumour catches on at work. As I said,nothing happened,but for some reason I am now worried about what stories will circulate around work.Even as i write this,i can see how crazy and dumb it sounds,but for whatever reason,alcohol just seems to put all these horrible feelings of guilt,worry and depression into my head,despite nothing actually happening.Why do I feel this way?

I know it might sound ridiculous,but im dreading going back to work.Why do I worry so much about what other people think? Im assuming its something to do with the fact that i was so drunk,that i cant recall most of the night,and am afraid of what i might have said or done. Alcohol seems to worry and depress me and make me focus on the negatives. Anybody have similar experiences or feelings after a lot of alcohol?
Thanks
