When will my dad die?

You shouldn't wish for him to die, because if he actually does die really soon, you'll feel bad about it. Don't avoid him, try and spend as much time with him as you can. You might feel like you hate him, but deep inside you really don't. All you want is for him to change, and the only way for him to do that is if you tell him how you feel. Sorry you have to go through this.
