I think I hate my guts.
Why do you hate your guts?
I wish I never had them and want them abcised.
Are you in physical pain? Seek medical attention -- maybe you have appendicitis. Otherwise, seek counseling.
I had that appendicitis taken care of a few months ago.
Go to the doctor and get some x-rays to see what's going on. Otherwise, if you feel you hate yourself emotionally, then talk to a friend to cheer yourself up.
