AIESEC and my social environment...

Today i woka up with a very bad dream...I don't remember exactly what it was. But there was a great deal of fear.Fear that I am leaving my "cosy little AIESEC world".
And I stayed in bed and thought ...Parting with AIESEC means parting with my current social environment. The kind of environment I like and feel comfortable with - young, ambitious, bright, energetic people.
Will I be able to find another social environment that will suit me?How long it will take...I really fear that, cause Sofia is a place where you feel extremely bad if you do not have a social circle...

Yet i hope I will continue meeting some old friends at parties. Yesterday I went to Lenka's party and Krasi was there. I know him for 3 years now maybe. And always when I meet people like him - that are already out of AIESEC, I feel so santimental about the "old days" when we were young, burning with the AIESEC idea. Did we burn out...or just grew up?
