Is this child abuse? what would happen to my dad if i reported him?

Parenting is not easy and being a child is not easy either. I am sure you and your dad are trying your best to do what is right. He sounds like he is strict and expects you to be and act responsible. Sometime it is very difficult to speak to our parents. If I were you I would write down my feeling on a letter and give the letter to him. Put the letter in his lunch box or on his desk or his pocket so he can read it in private, but do not give him in person. It sounds like you think very highly of your dad you should tell him this in the letter, also.
