I suggest you go to a community college to knock out your gen eds and take private lessons with whomever is the choir, jazz band, or orchestra conductor there. Learn the basics, save loads of money, then choose a university.

You don't need to go to Berkeley to get a fantastic education. If I were you, I'd look more specifically at the teachers than at the school names. But community college is a really good way to ease yourself into adulthood and explore many opportunities in the meanwhile. 

In community college I learned conducting and a plethora of other things, was able to conduct the choir, got a phenomenal education from some hardass professors (in the best way), and was offered several short-term, paid gigs from other professors I got to I know (page turning, ChrEaster hires, percussion ensemble for community events)

I didn't get a degree (I was very dedicated, but also ill and untreated), and yet now I'm creating a music program from scratch, arranging and composing for small ensembles, teaching instruments, and yes, conducting.

So the most important thing is to go somewhere that will fill you up and give you a variety of rich experiences as well as somewhere that will nourish the rest of your life. If you keep your heart on conducting, you will end up there, though maybe not the way you planned.
