I haven't had much of the experience with friends and have been a loner for a while, but if they left you their not much for friends. They might have for short term to protect you from gossip or something, or they turned tail and ran to the people they thought of as populars. If that's the case I'm really sorry. And it's probably not really good advice, but find others to hang out with and your friends might miss the good times and come back.
