Sent Facebook friend request, she's accepted everyone's but mine?

[beargojbitty]

I sent a friend request to this girl who I'd been friends with since kindergarten all through high school, and we were never BFFs but still, we had tons of mutual friends. She never accepted my request but went on to accept a bunch of others. I finally removed my requests because I was tired of seeing how many other people she accepted over me. The worst one was when because she tagged a bunch of mutual friends, I saw her mention our elementary school, and all the friends she had there, and I felt left out all over again. Sometimes I hate Facebook, it makes me paranoid, like what did I do to her to not have her accept my request? Also, when you suddenly realize that friends dropped you for no apparent reason and you happen to find it out when a mutual friend shares their picture. I'm thinking, wouldn't I have seen that firsthand? Oh wait no, I can't because I was dropped!! What the heck? I feel like deleting my account altogether...
