Relationships and undergrad formal

I had my year-end undergraduate formal three days ago and I still can not get over what a bad time I had. It was all about expectations...

Several things:
1) It was a social WAR out there- it takes a lot of confidence, a lot of moves, and a lot of savvy to navigate a crowd of people you don't know well. I for one am terrible at it! How do people cope with it? From my observations:
a. they have a significant other or a designated person/group who is their safety blanket
b. they are drunk
c. they are just that good and have the skillz
d. they are oblivious to the awkwardness of the evening and could have gone on a date with a cactus and still had a good time

I unfortunately were none of these things...it is no wonder I did not have a good time. (But on an optimistic note, had a better time than if I were embracing a cactus...)

2) I was snubbed several times and I could not help but take some of them personally. It caused me to re-evaluate friendships and tempted me to write some off. This is NOT a good idea because in large social events like this, no one EVER acts like themselves (plus the alcohol), and people are much more concerned about appearances than anything else. So I am working hard to convince myself to have confidence in my friendships and that one debauched night of snubbery means nothing.

3) How to re-write the evening so I feel better about it? So I feel better about myself?

The conclusion of the night: DON'T TAKE ANYTHING PERSONALLY! IT IS NOT PERSONAL!
