As someone who is concerned for you and not just trying to confirm my own biases, I think it's worth saying that when you're in high school you do more than just run. I took AP classes like you and ran maybe 40mpw and between all that I barely had time for 8 hours of sleep and any down / social time at all. Theres no way I could have gotten 8 hours or had as many friends off 100mpw as I did off 40, and I probably would have needed more like 9 hours a night had I been running that much. You really need to think about your priorities.
Also, hear this. My freshman year, with a few weeks of 30mpw (and almost nothing before) i ran 24:00min 5k cross, down to 5:15 mile at the end of Spring track off averaging maybe 35mpw. Through high school I never did more than 50mpw, though by end of sophomore year my pr's were down to 18:00, 10:35, 4:55, and each dropped consistently throughout high school. These times aren't great, but it is a lot more rapid progress than you seem to be making literally running twice as much, and I would argue from our starting times that you may be a more talented individual than me.
Finally, I'm running in college now, have gradually worked up to 60-70mpw and my PR's have dropped rapidly. I now run well off of more mileage, but that's only because I waited in my development to really train with more volume. I still love running and have competitive desire years after high school, which I promise is not likely to be the case with you if you continue training so much, sacrificing so much of your time you could spend on school or with friends, for results that can be attained by someone with less talent off of less volume. If you really want to dedicate yourself to the sport, you have to train smart and think hard. Whether you choose to really go after the mileage in high school or not, I hope you can conduct yourself so that you actually enjoy high school, running, and life in general.
