I don't have any advice or help for you because I'm in a somewhat similar situation as you. I was also a good student (not quite straight A, but close enough) and thought my education would also give me some form of agency over my life. That, of course, turned out to be completely untrue due to various factors outside my control. I also thought moving out of my small town would give me a fresh start and allow me to finally live a normal life... which never really happened either.
All I can say is I'm sorry this is happening to you, comrade. If you need to talk or vent, my DMs are open
I hope to see a free Palestine within my lifetime, and I hope one day you'll get to live the rest of your life in your homeland in peace and freedom. Stay safe, comrade.
