Dad keeps throwing away my college offers in mail without even telling me

Hey guys I am going onto Reddit to get a second opinion on this. I'm in the process of looking at colleges and I think my stats are quite good, I made sure to let colleges mail things to me so I can check them out. However, I just found out that my father would almost always grab the mail, look through my stuff without permission, and throw it away. Adding on to that he decides which colleges he wants me to look at and I've told him various times to give me a chance to look at them which he obviously always ignores. I don't have a very good relationship with him and even at my age, he thinks of me as a joke. It hurts because I just feel like even at a young age I never get a say or chance to do anything I want and now that I am growing up I can't even look at colleges without him breathing down my neck. It's making me crazy and I feel so damn hopeless.
