I am a stupid girl who rejected my mate!

They say when you meet your mate, he will love you unconditionally. They will not judge you and you are the only person that they will love and want. That was what my parents told me, but after their car crash, I can never forgive myself. You see I caused their death and now I hate myself for it, I don't deserve anything. I don't deserve a mate, I don't deserve love and I especially don't deserve to live! But I'm alive and that is why I rejected my mate.
