I’m a homeschooling parent with a master’s in theatre. I attended grad school in Texas because I had a young family at the time and couldn’t move, but I was told many times that it was ridiculous to study theatre anywhere but NYC. I sort-of agree. College is about learning and growing outside the classroom just as much as IN. The first part of your post immediately made me think of CALARTS, which has one of the top animation schools in the country. I would think anyone interested in acting could find numerous unparalleled opportunities by simply living in or near Los Angeles. However–it isn’t a liberal arts college, so you’d be limited there.
As for the homeschooling side of things, you sound very articulate, confident and driven. The common app will ask you to explain “any gaps” in your formal schooling. I would think any school with a “rebel spirit” (Evergreen, New College of Florida, Colorado College, Bard–to name a few) would really appreciate your being straight up honest about how your needs were not being met in a traditional school environment.
My son is technically homeschooled but he’s been attending the local community college as a “dual enrolled” student for the last year. I’m afraid I don’t have specific knowledge of animation programs other than Calarts but you might look at Marlboro, which is tiny and I understand they help students put together a plan of study guided by their own interests. Good luck to you.
