I'm going to post not having read this entire thread. I just want to mention that you do not have to go to a fashion school to be in the fashion or apparel industry unless of course you are trying to be a designer or something else that requires techincal skill. The career range in fashion is the same as in any other industry from the "glamour" end (modeling, agent, designer) to more creative aspects (marketing, advertisting) to business (legal, accounting, sales). For marketing or journalism you can go to any college and a degree and then seek fashion related jobs and work you're way up and around.
So my advice is to intern and read, read, read. Then you'll start to uncover things about the industry that may be of interest to you. Also, I would suggest if you're old enough to go out to events and meet people and talk to them about what they do.
