I was the same. Not home-schooled, but the only time I was there was recess - had to walk home for lunch. Pariah at school. All the kids at the hall weren't 'spiritual enough' and were 'bad influences', so I had no friends.
I read a LOT. Books became my friends. It was no way to be, in your teens. I'm sorry you are going through this. Soon - SOON, not their kind of soon, but you can put a date on it - you will be able to leave You will have to work hard for low pay, and get your education, but you will make friends at work and school. Life will be so much BETTER by the time you are 20.
I did it, and so can you. Hang on, and continue to communicate. That's what we are here for.
