School Stress College

I’m so stressed out by my sophomore year of college. I’m doing history, which are my weakest subjects. And I’m so stressed out rn because my teachers aren’t allowing me to submit my assignments late saying my accommodation's aren’t retroactive. I need to pass these classes for sap so I can get financial aid next semester and I need to have sap so I can receive loans which I use to pay for my car repairs where it recently costs 4k and now another 1k as I wait for my refunds. Me going to school use to be easy peasy until I broke my car which caused the expensive repairs and btw you can’t get loans without sap, while door dashing essentially starting a job. Starting a job messed up my dopamine receptors that I can no longer focus and retain. Right now, especially with unmedicated adhd, and people don’t realize how hard it is to get medicated and how long have to wait. Heck I’ve had mental issues for 20 years now and I’m still unmedicated. They keep telling me oh I keep having breakdowns at school and in public, then they say I should easily get medicated, then I go to the hospital and they tell me that’s how’s the system works. Anyways I was saying I don’t retain the information like I usually do and tbh I use to like studying cause WELL it’s SO EASY and rewarding (well it use to be). My professors would let me submit things late because it wouldn’t really affect my grades anyways. Now they won’t and they know I’m struggling so bad in classes. At this point I’m convinced I have dyslexia but not diagnosed. My exam be tommrow morning and I’m studying but retaining information so I’d rather just watch my favorite streamer. Idk what to do guys… Help!
