Failing is OK as you can see from history:
"Caesar served in 63 BC as a quaestor in Spain, where in Cadiz he is said to have broken down and wept in front of a statue of Alexander the Great, realizing that where Alexander had conquered most of the known world at thirty, Caesar at that age was merely seen as a dandy who had squandered his wife's fortunes as well as his own."
You'll be depressed for a while, but soon you realize that you have gained valuable lesson. Failing is something that everybody does, and it's part of everybody's life. (There is a physical reason for this: entropy* )
Hack: Accept yourself, and don't try to be social. This takes the pressure off of being social, and enables you to handle social situation in relaxed state.
You ain't perfect - nobody is. Remember and accept it.
