I hate myself for thinking relationships are worth the pain
Why don't you think they're worth the pain?
I get dumped a lot and I get hurt a lot by my friends.
It sounds like you're frustrated. Talking to a counselor could be really helpful if you have trouble with relationships.  It would definitely make you feel better.
Nope, I'm going to delete myself and start over.
I don't understand what you mean by delete yourself, but I assume you merely mean taking down your online dating profile.  Don't do anything more drastic than that, because dating is not a pressing need in your life.  You can happy without a boy- or girlfriend, and so you can just wait until you meet someone you really like.
