My best friend

My best friend just got a girlfriend, and now she barely talks to me; and when she does all we talk about is her girlfriend. I still have friends, but it hurts to lose a BEST friend. I miss our friendship. After that my depression has become much, much worse I relapsed, and I'm miserable. I have a friend, he's sweet and all, but it's weird when I just want to hang out with him and everyone asks if we're going out. I just want to have an averagely normalish life.
