“Even though I’m taking accelerated classes, they don’t believe I will be able to go to college, and even say they’ll kick me out of the house when I’m 18.” Is that a statement that they certainly will, or that they may kick you out of the house if some other conditions do (or do not) come into play?
It is unfortunate and it must be terribly difficult for you to negotiate the space between your personal growth and your parents’ needs and demands. You seem to have an astute ally in your school counselor, nurture that relationship.
Perhaps you can also build enough trust with some of your teachers and help them to understand the necessity of responding to student emails (to your emails). Continued calls to your home, which result in heightened tensions with your parents, are more readily within your control if you can avoid having the calls attach.
I would warn against trading in one emotionally pressure-filled and unsupportive environment (home) for another. That could be a minefield.
Graduating early for someone who is, or will have, essentially repeated instruction due to a lack of language proficiency suggests you may be in a better position to transition to college life than other students who leave early, who are, in fact, a year younger than the conventional high school student.
Research your target college’s policies for admission of the high school student who lacks a HS diploma, as those colleges and universities do exist. (Note the earlier comment on preparing to be a competitive applicant among your peers - other early entrants to college.)
As I understand it, you will need to have exhausted the offerings of your high school to have your need for entering college early seriously and thoughtfully considered.
