I feel you, Marion.
For seven years, I've built a social life entirely on drinking. That means that I chose my partners and my friends based on how often they could go out and drink with me. I'm not proud of it, that's just the way it was.
I got lucky and am now with a man who doesn't drink. The friend situation, however...it seems like now that I don't drink, no one wants to hang out with me. I'm 25, and it seems like the only people my age who DON'T drink don't do so because of religious reasons or something. And so it's hard for me to make friends.
The loneliness...it sucks sometimes.
