I resent my parents for being alive and having me because they're the only reason I have to live. I wish they died so I could go more easily.
How long have you felt this way about your parents?
I've wished they died or disappeared since my youth.
I'm sorry you're feeling so down.  Instead of directing your bad feelings towards your parents, which is selfish, why don't you try getting some help?  Talking to a professional about it can be very therapeutic!
Yiff me.
I am just trying to help you. I think that it shows that you need help when you wish bad things like that to happen. Talking to someone can help you figure out these issues.
