Just wanted to say I'm feeling the same way, still reeling from losing my old friends from high school. I read the situation wrong I think, I knew that the four friends were really close, and that I was a part of it, but I was wrong :/ After high school, they're friends with each other still, but I'm out of the picture. So now I need new friends, and don't know where to go. I just want what I had with my "best friend", just be able to go into Chapters (Canadian bookstore) and read together, going window shopping (or le gasp, shopping when it's the beginning of the month) or just talk about our lives without having to worry about saying the wrong things. I don't wanna go clubbing or go out every night, I think I would die. I have my BF, who's wonderful, but I miss having girl friends. I personally don't feel connected to people online anymore, they disappear and forget you too easily from previous experiences :/
You're definitely not alone, even though it feels that way.
