Change?!?

I don't understand my parents, nor anyone else for that matter. Everyone keeps telling me to change, become what everyone else just knows I can be. Someone beautiful, smart, kind, blah, blah, blah. I can't be what they want me to be, I can't change! Why doesn't anyone get it? It isn't as easy as repainting a room. I'm a human being (ok, so I'm not the best example of humans, but you get it). Get this, my mom grounded me from cheerleading because my car ran out of gas on the way home from working on a school scoence project for electrical engineering. First I tell my mom I have little knowledge about cars, then she tells me not to act so stupid, that I know what goes on in my car. Later, she says I'm being punished for always acting like I know everything, even though told her that I have no idea about cars!!!! The only thing she taught me from all of this is that, even though she told me that I could call her if I need help for anything, I can't ask for, or expect, any help from her, unless I want trouble for not being perfect. Screw it, I can't handle it anymore. I just want to scream!!! Oh well, perhaps she'll see what she's doing to me. Perhaps...
