You're father sounds very abusive toward you and your mother too. He is just a bastard-that's the word that comes to my mind. Hopefull with your smarts you can go to a great college and get away from them, keep up with the studies, I know you will, you sound very intelligent, and curious. You are NOT useless, you are more useful than you will ever even know yourself. Stay the straight path, and I'm sure you will be a success at whatever you choose to do with your life.
