i think i may be completely screwed

so for context im 17 and in my senior year of highschool. middle school i was a shut in, i didnt talk to anyone or do anything and then during covid i was “homeschooled” where i did completely no school. i get into highschool and go to a HUGE. and when i say huge i mean huge school with almost 3000 students. my highschool experience has been EXTREMELY hard and i found out (while at school) last year that my dad had died. we werent close due to him being a deadbeat but i always figured we had time to fix our relationship. it crushed me when he died and i tried to cope with smoking weed and drinking and hanging with the wrong crowd and bc of my dumb decisions my life has gone to shit. ive never been a great student but i passed most of my classes, come senior year and im completely burnt out from doing nothing. i only have to take 3 classes and i need 2 credits left to graduate and i cannot do it. my english class is so unbelievably hard and i am really bad at math but those are the only classes i need left to graduate and from how its looking it seems like theres no chance. i have to move out by october because my mom is moving to pretty much the farthest place you could be from where i live rn and ive moved my whole this is the first place thats felt like home so im trying so hard to fine an apartment with my sister but we both just lost our jobs and nobody is hiring. on top of that my car just broke down on itself (also my childhood car that was very sentimental to me and took me everywhere around the US) and is completely unusable so getting to school is a whole other problem on its own. i just cant do it anymore im so tired of living like this it makes me think if life is this hard because i know life is hard i know you just have to do it and get through it but i dont even know where to start when i never envisioned myself living this long anyways. i want to graduate so bad. anyways any advice would be appreciated thanks!
