Is there any way I can become a FASHION DESIGNER without going to school?

I have done some extensive research to see if going to college is actually worth the time and the money.

I am currently eighteen years old. Going to High school is SUCH a drag.

The way i see it is:: whats the point of wasting my time in a classroom where I dread being in?

My dream is to become a fashion designer not a doctor! Why do I really need biology 30? it is , more likely I'd forget most of everything I learned in the class in less then a month. I just don't see the point.

 I feel like I should just drop high school and start my fashion design career learning from books, website and YouTube. I consider myself to be a very independent person.

In for 2.5 years I have gone to a high school were I was in a "self-directed learning program." It wasn't easy to begin with but I eventually got the hang of teaching myself without a teacher. Basically that's what the school was all about. I would come into the building meet with my teacher adviser and then head onto the "learning floor" pick a desk where I wouldn't get distracted and start working on my learning guides (modules). There were about 2 seminar classes per week and that's it. I mean it was so chill.

But the only real problem I had was the fact that I just couldn't teach myself math. I would spend hours at the math desk. I knew I needed a real math teacher. Theres some things I can teach myself like social and English but then there is math - the most dreadful subject of all. The one I've always had problems with even when I was younger. So the second semester I decided that I would move to a normal structured high school.

Boy was that a mistake. I mean, I'm doing well in math 20-2 now that I have a teacher.
But what really grinds my gears about being in a normal high school is the fact that I actually have to listen to the teacher's mombo jumbo. Half the time the teacher doesn't even teacher because the kids are having their a.d.d moments and the teachers have to stop and get them settled.

God, I really hate school in general. I used-to be able to study for science, but now I just don't have the motivation to study something I don't want to. My motivational drive is in the concept of art and fashion. I have always had a more creative mind, rather then a mathematical one. Everyone has their own strengths. They may solve a problem a different way then me. I personally don't think HS is for me. Its wasting a lot of my time. Remember Alexander McQueen? Yes, how can anyone forget! If you don't know who this brilliant man once was then go back to your cave. You may be surprised to learn that he too was a high school dropout. He later somehow got into (a dream school of mine) in London called  Central Saint Martins College of Art and Design. He is my idol.

However, not everyone I know is exactly on board with me. I told my mom I was going to dropout yesterday and It was like an Earth Quake hit the room all of a sudden. Shes yelling and telling me that I'm going to end up like my brother; a unemployed father. (well, at least he graduated from hs, i guess) She says I'm never going to find a good job if I don't take the first step and finish that diploma. But she doesn't understand. She's a nursing attendant for Peace sakes! And my dad? Ha! whatta Joke.

If anyone is still reading this post, please tell me what you think. Can a high school dropout really succeed in this competitive world? Or am I only lining myself up to be another mim. waged patty flipper?
