The first time I'll be going to public school will be college(If I do decide to go). With the reasons you've listed, homeschooling is probably going to work very well for you.
I'm not antisocial because of my homeschooling at all; I just have a small group of friends, which grows from meeting people through those friends and through artistic environments and happenings. It works better for me this way because I get to meet people of different backgrounds, personalities, and creativities. I get to meet people who are as crazy and ridiculous as I am.
Which homeschooling program will you be using? American School is the norm in high school correspondence programs, and it's what I have, but I wouldn't recommend it if you're seeking more challenging school work. I started 9th grade in June and finished it by early August. When I got my 10th grade math course, I finished it in a week. I'm planning on officially graduating and getting my diploma from them sometime next year, and then finding books that bring more of a challenge at the bookstore, in the subjects that I'd like to learn about further. If I graduate next year, I'll be 15. I could just go on to college immediately, but it would be smarter to get jobs working with art/music/writing/etc., to gain work experience, better my portfolio, save money, and also do some more fancy book learning to be better prepared if college slaps me in the face.
I shall shut up now.
Good luck, I quite a very great much of a lot bit hope you enjoy homeschooling.
