Can you get your brain damage recognised as an official disability. That might assist you getting admitted into University or government jobs. I doubt you want to play the disability card but future you might forgive present you. And the best case scenario is that your brain gets better and you do great in your job.

Changing the subject you say, "When I've been able to rest for a extended period I feel almost like I used to, but everything degrades whenever I try to actually do something". People recovering from CFS or long Covid are (I think) given explicit advice to not push yourself because you will stay broken. I'm really sorry because that advice is not compatible with A levels study and the expectations that you have of what you _should_ be able to achieve.

Good luck
