Friends deleting me from Facebook. Why?

[Dr. Jay]

So, one instance, I liked a friend's status and he commented and said, "Hey, long time no see blah blah blah, how you been" and I replied hey good blah. a few days later I went to his page and it said add friend. and I was like WTF? same thing happened with a few other good friends, that I was close with. I know it's just facebook, but that kind of hurts my feelings. I don't have hardly any r/l friends anymore. I hate my life. What did I ever do to them? I was nothing but nice. Why do people hate me so much. I hate being weird, this isn't even a question anymore, I just wanted someone to "talk" to since I have no friends.
