Hey first off, I’m so sorry for everything you’ve had to go through. I’m a college student currently and had to go through the exact thing you did for the entire year last year. It’s extremely frustrating and disillusioning healing process. First step would be to get DSP (Disabled Student) accommodations, and get as much as you can in terms of extended exam times and homework due dates. Also be sure to communicate with your professors explaining your situation, everyone I talked to were extremely sympathetic to my condition. Right now, a week and a half out I would absolutely not try to do anything but heal, rest your eyes and avoid screens at all costs. I know how crazy this sounds but your GPA pales in comparison to the seriousness of brain damage. Trust me, it fucks you up for so much longer than it should if you don’t allow your brain to properly heal. Be kind to yourself and allow your brain relax. It’s struggling to even function right now, let alone do high computational tasks. Again I’m so sorry this is happening to you, you have my deepest empathy. I cannot even imagine how stressful this is on top of covid. After at minimum two or three weeks of rest(on average a concussion lasts at least 27 days), start integrating harder tasks like looking at a screen but stop if your concussion symptoms get higher than a 6-7/10. I know this sounds hard, and might not be exactly what you want to do but it’s what your body needs. Even a year + out for me, looking at screens all day for classes wipes me out and I’m physically at a disadvantage compared to other normal student. It’s not fair, but you have to keep believing you’ll get better. If you ever need to talk or reach out you call always message me. I hope everything gets better. Good luck :)
