Hey there, have you tried meetup.com? Depending on where you live, there may be an abundance of different groups you could try out. For instance, a few years ago before I met my wife, I joined an outdoors group that I went hiking with, and a vegetarian group that had bi-weekly vegetarian pot lucks and met at various vegetarian restaurants. I am not good at maintaining friendships, but I did meet quite a few nice people in those groups.

EDIT: Also, welcome to the forums, hope you find some support and comfort here.
