OP, I feel for you. Many on CC push “fit” for college but when it comes to H.S. they have more of a “suck it up” or “stop complaining” attitude. I do agree with @bhs1978 and others to try to make the best of your situation, but I also feel that a challenging and positive high school experience are extremely important particularly for an adolescent. I agree with you about weighing other options. I can’t speak to graduating early, but it sounds like it might be worth exploring. Talk to others who have done it (maybe search for threads on it in this forum).
Explore transferring to another public. Some states allow you to transfer to a better school if your school has a low grade. If you are going to transfer I wouldn’t necessarily default to the second closest one. Look around for charters, or the best high school for you. Is car pooling an option? Will you be driving and have access to a car in the near future? Can you bike? Could you approach your parents about driving for you in the short-term (until you can drive or find a car pool) and maybe giving back to them in exchange (cooking, cleaning). I personally would never ask for this from my child, instead I advocated vigorously for school changes for my child, but your parents obviously have a different outlook on this. Is there a school where public transportation is an option?
Also, if you find a school you love, gather your transcript, a letter from a current teacher/outside person if possible, a resume or a list of your activities, test scores (all schools have test scores from middle school, don’t they?), and try to get an appointment with an Assistant Principal or the Principal or anyone who will meet with you. State your case. This has worked for us every time. We were told “no space” but when I sent the paperwork, followed up with a passionate plea, and/or they met our daughter, they suddenly found a space.
In terms of transferring, there are some things I can share with you (my junior daughter changed schools from a good private to an IB public in junior year, and also from a low performing public to the highest performing public in another school district in elementary school.)
–it will be harder to get leadership type positions when you come in as a junior (though my daughter did get one this term and for next year).
–In her case, outstanding teacher recommendations will not be an issue—she is in a small IB program though. Will this be the same for you in a large class?
–Check about curriculum requirements (probably not an issue for you if you stay in the same public school system), as this was an issue for her. For instance she couldn’t continue Latin which she loved as it wasn’t offered in her new school. She had to take HL Chemistry with no prior chemistry (this caused a lot of stress and tears for her because it was so hard at first but she has mostly caught up).
–Another drawback was rank: her private school only had unweighted grades and the public wouldn’t even agree to weigh “advanced” math classes that were for only a select few. All of her public school peers get weighted grades for 9th and 10th grades for Honors and AP so she will be in top 10% but would probably have been on of the top three students if she had attended this school for the first two years.
–Her workload is much heavier, more papers, presentations, no study halls, no handholding. There will still be some poor teachers no matter where you go. You may find a more competitive environment stressful, too! Hopefully less stressful than an unchallenging one.
–Individual college counseling is lacking (again these were differences for her with the private to public transfer)
–If prom is important to you, that could be an issue if you are quiet like my daughter and have a small social circle (only mentioning because there will be both big and little transitions, social as well as academic).
In the end though, the transfer was worth it, and we have no regrets. I hope you find a way to get in a better place for next year whether that means staying where you are, graduating early or transferring.
