Wowow. So many responses. I'm gonna try to address everything here, so let's go.
@ Trefle, Mr. Brightside, Zanosuke: Actually, my mom suggested I see a therapist (I told my mom a little about how her and my dad's arguing [which contributes to my mistrust of others] affected me: I haven't been able to observe really any
normal relationships and so I don't know how a normal relationship should go, and that I have trust issues because I if my parents can't even get
their act together, how should I trust others to treat me with dignity. And my past experiences with peers haven't left me optimistic either. [All the other stuff I mentioned is still stored away inside of me.] So the topic has been breached at home, and after reading what you said, I'm leaning toward asking about seeing a therapist sometime. I am making small steps toward addressing the issues on my own - back in Acting class there was a sort of "share your dark secrets day" so people could get stuff off their chests and I mentioned myself considering suicide and even came out as bisexual and everyone was very supportive, so that felt really good.

But I didn't tell them everything, and the people closest to me have no idea. Maybe when I'm in college and calling home I'll pull a "By the way, I'm bisexual" before hanging up. Now THAT would be interesting...
I do have outlets, though - writing and drawing and daydreaming about other worlds (which I subsequently write about.) I actually do want to be an author. Writing is especially good for me since I feel like I have some control. I have the control to create a more accepting world, a world where there is no prejudice.
@ Otaking: I haven't totally decided where I'm going to college just yet (I do have a top three, though.) My dad is going to help me with scholarships, at least. I'm ready for the world, bring it on! And trust me. Once I'm in college, the facade is gonna be shattered into a million pieces. I'm going to stop hiding behind parent-approved clothes and parent-approved beliefs and finally... well... BE MYSELF for once, DAMMIT! Once I do apply and start getting accepted I'll start looking into jobs and housing.
@ Hexr: I don't think you sound patronizing in the least. Thank you. Usually I manage to feel okay, but sometimes, as I said before... I just look back on what a horrible person I (sometimes) perceive myself to be and that's not fun. And I do try to avoid jackasses whenever possible.
@ Louisa: Writing helps a little, since I can channel some of my feelings into what I'm writing. Also, despite my feeling a bit odd when reading what people are saying to me, I do feel better that people are able to understand and sympathize with how I feel. I realize that I'm not alone (I didn't necessarily think that before, but nobody seemed to notice I was acting a bit differently, feeling differently.) I will continue posting. Because... having it all OUT for once, in words, being able to recognize my thoughts and put them into words, at least... it just feels good.
(I realize that I'm sort of villainizing my parents here, and I don't think they deserve that. They try, at least, and I know they worry about me, but I'd feel uncomfortable talking about this with them. I don't have words to express WHY... but I would.)
