Unbelievably Lost and Confused

I have no idea what I'm doing with my life right now, I feel so confused and lost. It seems like lately, I've been changing my life in a decisive and dramatic fashion. I've had my eyes set on such impossible and bizzare goals. At the same time, I question whether or not I'm making the right decision. Am I screwing things up rather than changing my life for better?
I quit the Ultimate Frisbee team because it took me two years to realize that I never liked the sport in the first place. What I liked about it was the feeling of togetherness when I played side by side with my team members and the feeling that I belonged. I only joined in the first place because my friends joined and I didn't want to feel left out. I remembered in grade eight when they all joined the Library Club and it seemed too boring for me so I didn't join. I ended up sitting alone by my locker whenever they had meetings; I didn't want a repeat of the same events with Ultimate. So for two years, I spent every practice staring at my watch, hoping for practice to end soon. My skills improved, but not enough for anyone to pass to me during a game. I would run around for two hours, get exercise, but never get the disc. My friends were (and still are) crazy about the sport, I played along, but always felt like such a fake afterwards. I guess I'm finally tired of pretending. My friends don't quite grasp the concept that I don't like Ultimate and just think that I'm being irresponsible and lazy. I would explain again but its not worth my time to do so and I'm not obliged to explain anything to anyone in the first place.
With my friends, lately, I've been confiding in my guy friends more than my close girl friends. Around my female friends, I feel the pressure to act like a goody-goody. They are the type of people who would feel awkward and embarassed if the subject of sex ever came up and have probably never said the f-word once in their lives. With my guy friends, it seems so much easier to confide in them because there isn't the pressure to censor everything before it comes out of my mouth when I feel the need to rant. But at the same time, I miss the closeness that I share with them, but then I don't really want to seek them out and talk. I guess the arrogant side of me thinks that if they don't come to me, why should I waste my time going to them? I don't know whether I want to stand out amongst my firends or fit in. When I stand out, I feel lonely and left out, but whe I fit in, I feel as though I'm just a part of the crowd and not a distinct person.
With religion, I am especially confused. In a sense, its too deeply imbedded in me for me to ever practice Wicca or become a Buddhist or anything like that, but I always feel so fake whenever I sit in a church. Most of the things that the pastor tells me not to do, I don't want to stop. As much as it sounds so great to many people to be all moral and everything, its just not me. There's so many don'ts in Christianity. Don't think lustful thoughts, don't masterbate, don't date non-Christians, don't have sex before marriage, don't swear or take the name of the Lord in vain. Most of all, the thing that disturbs me the most is how intolerant Christianity can be. I remember that one sermon that probably planted the seed of doubt in my mind. Apparently, according to my pastor, being homosexual is a sin and isn't something that you are born with but something that you choose. Despite being straight, this is exactly the opposite of what I believe in. I believe that people should love whomever they wish without being prosecuted.
With my future career, I want to be something that involves writing. I want to be a journalist and make a difference in the world with my opinons. My goal is to some day, be as influential the way Oriana Fallaci was. But at the same time, I know that being a journalist is not a very stable career and not very many journalists manage to make it big. Also, being a successful journalist would mean sacrificing the opportunnity to get married and start a family. Even though I highly doubt I'll ever be a wife and mother, the idea of living alone for the rest of my life does not sound very appealing. Plus, I could be sacrificing this and still turn out to be unsuccessful. I've also thought about being an English teacher. I had the chance to teach a Drama 8 class the other day and it felt really good. The teacher thought I was great and I had a great time. On the toher hand, being a teacher isn't exactly feeding my ambitious dreams. But educating the society of tommorow is a very rewarding thing. I don't even know where I'm going for college yet. I want to go somewhere far away, experience life, see the world, and get away from my parents. But I know I can't afford it because my parents never started a college fund for me. Despite my Honour-Roll grades, my parents never felt that they should save up for my education. In fact, they were about to start a college fund for me a couple of years ago when tehy learned that the Canadian government gives $500 to your fund or something, but they gave up on the notion when they realized that the child had to be under 12 or else the government wouldn't pay you anything.
Argh, I hope I'll pull my act together in the end.
