I've been there. The resolution that got me through:

Be the fun-loving gregarious person you are no matter what. Don't accept the coldness and aloofness as a reprove. Smile when you see a scowl. Know that you know better. Remember to first give out what you want to get back. Eventually you will attract people of like mind. We are out here.

I know I sound like a fortune cookie, but it worked for me.

Oh, and send 50CHF to EF for the advise.

Cheers!
