Parent problem -- Help please?

I've grown up in a church family my entire life. Everything's pretty much been normal and functional. Recently in the past year then my parents have been really protective (maybe they have all along, but I never noticed) and it's really starting to take it's poll on me. I'm not just talking about the major things-but the little things too. For example, I like getting somewhat of a natural tan before summer kicks in. But my mom's mom had cancer(not even skin cancer) and heaven forbid I lay in the sun. I asked if I could get a sunscreen that only blocked UVB rays so I'd get a lil tan and heaven forbid!! So I'm rebelling and tomorrow I'm kickin' back in my bathing suit in the sun after I go buy my own sunscreen. My dad doesn't really give me much freedom. I'll see him checking up on my facebook, reading text messages, and he doesn't even want me to stand by our road because "when people speed, a rock could fly up and hit you". What. The. Hell. They don't like me wearing shorts above my fingertips and when I wear a bikini my dad says "where's your shirt?". Honestly, this isn't going into much detail. But I can't explain how frustrating this is and how much I hate it. Really guys..

And then this last part throws everything off. My dad used to do rodeo's, ride wild bulls, get in fights, dip, chew, and anything cowboy you can imagine. He was as close to "wild" as you could get. And now he's all protective and keeping me from the life that I want. Then my mom would always run around Arkansas in the woods and be gone for 12 hours at a time, she'd drink, get in bad situations with men, use police as designated drivers(don't know how she managed that), party, you name it.

I don't really know what I'm trying to ask out of this, but it's really killing me. The more they're protective, the more I want to rebel. I haven't even gotten to the "big stuff" yet. I just need to know how to help this out, be less rebelious, or anything. Y'alls answers are greatly appreciated.
