First, finish high school.

Second, don't go anywhere until you're 18, because if your dad is really that controlling, he will be legally able to make you come back if you're only 17.

After that, sure, why not? If you're going to do something like that, do it while you're young. In 20 years you'll regret the things you didn't try, not the things you did. Trust me, I'm 48.
