find my childhood best friend

We don’t talk anymore. At one time we knew everything about one another and now we know nothing. I don’t even know where she lives. I want to know her again. Even though we are very different from each other I think we should be able to at least talk on the phone. I am afraid I was not a very good friend but I don’t think she was either. Anyway I don’t think that should keep us from talking now. She is an amazing person, I should at least tell her that.
