You wont ever fully get over it. The best you can do is remember them for their acomplishments. I understand, I have had the same thing haoppen. I'v elost many friends and family to cancer, and aircraft accidents mainly with American Airlines. You have to pull strong. It's the only thing you can do right now. I couldn't imagine what I'd do if my mum died. Some people shouldn't be greatful to have parents because they aren't really parents. Have you tried to get to no ur dad better? Maybe if u give it a lot of work, he might open up. There must be a reason he hurts you. You shouldnt have to put up with that.
