I'm not sure what to do

I'm located in Texas and I can speak but not write Chinese. I'm basically left to my own devices all day so I don't know if that counts as home schooling, but I do study the same amount as public school students. I am not allowed to work, cannot drive, and basically have no obligations. I don't have a HS graduation or GED, but I can get a homeschool diploma whenever I decide to nag my father about it 

Your first step is completing your GED. You'll need that for many colleges.

Much easier is just having his dad do a homeschool diploma, which he said he could do.  I personally never recommend the GED if you have a diploma option - it has less stigma attached.
