Transferring middle of senior year?

I just began my senior year of high school, and while this should be really exciting, I’ve been having a lot of anxiety. My mom got married recently, so we moved outside of my school district so she could live with her new husband. We never changed addresses with my school so they currently think I’m living in the district, but I’m not, which means they can force me to transfer if they find out.

I would’ve transferred already, but the high school I would have to go to instead is much worse. I’m really scared and trapped. With college applications, I don’t know whether to put my old address so my school doesn’t find out, or my new address. So here’s my question.

If I’m forced to transfer midway through the year, will that reflect badly on my college applications? And if I’m forced to transfer, should I just do online schooling? The idea of spending my last few months in a terrible school with strangers is making me really depressed. There really seems like there’s no good way to solve this. I hate breaking the rules and this is giving me so much anxiety, so any guidance would be greatly appreciated.

Are you sure it is required that you transfer? Usually you can finish out a year, or even finish out high school. Most high schools bend over backward to help you finish.

Most high schools want their class of students to graduate (for their graduation stats).
Write your new address on Commonapp.

If you put your old address on the common app, colleges might send you info to the old address.
I assume you are still attending your old school?
Could you live with a friend for the rest of the year?
