It is hard to work through something like rape. Have you considered counseling or a support group for moving through the feelings you have regarding that?
I know you know that it wasn't your fault. You can't change what happened in the past but you can learn to not dwell on the memory and to forgive your attacker.
I don't believe no one likes you or that you've alienated everyone. That sounds like something I've told myself in the past, but it isn't true. It's a lie based on self esteem, and that can be mended.
