I think I despise my dad and I wish he would disappear and not exist anymore
That sounds harsh. Why don't you want him around anymore?
Then I wouldn't be forced to listen to him anymore
You may feel that you want your dad to disappear now, but if he did, you would find yourself suffering some long lasting emotional damage without him. Communication is a key part of a relationship, so sit down and talk to him about your troubles and get on equal ground.
It's really not that bad, my dad makes me upset sometimes.
I still think this bothers you quite a bit. Talking to him or your mom about this might help you deal with your feelings. You dad only wants the best for you even if you can't understand it.
