I had a pretty clear plan: Apply to Oxbridge. Failing that, do a degree apprenticeship at GCHQ etc.
March last year my friend was attacked by bullies at school. I tried to help, I was kicked in the head multiple times. The perpetrators got away with it because of our pathetic "justice" system. I was off school for 6 months and I have post-concussion syndrome. I am now below average intelligence. I am constantly fatigued. I have constant headaches. When symptoms are particularly bad I can barely walk or process speech. 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. My doctor has been helpful and sympathetic, but I am still waiting on specialist help via the NHS.
I am a year into my A levels. I have done nothing but study this year. I wake up, go to school, stay awake with caffeine tablets and strong painkillers, get home, revise, then sleep. It's the same at weekends. Studying is extremely difficult and I retain far less information. I optimise my time with Anki, spaced repetition, and Obsidian. Despite this effort, I had to drop an A level (further maths), which made my already infitesimal chance of Oxbridge zero, and I am barely staying afloat in other qualifications. My current A levels are maths, physics, and compsci.
I don't do much programming now, but when I do I'm significantly worse. The most noticeable difference is in my working memory; where previously I would just write something, I now become overwhelmed if I don't meticulously plan and break the problem up first.
I have no clue how to continue. At the current rate, I will get good enough grades to get into one of the local unis. I think I'd be OK with a computer science course, as I already know much of the content. However, I don't think I can do an apprenticeship or other form of inflexible work - I am not reliably awake, and I'm simply not that intelligent anymore. I plan to take a gap year whatever I do to get some rest.
I've considered trying to work as a freelancer running a software business (after A levels/degree), as that would hopefully allow for more flexibility regarding symptoms. However, I have absolutely no clue how I would go about doing that, or if it's a good option. I can do desktop or web dev, I know Python, Rust, and TS well.
I'm not really sure what I'm asking. Is the freelance idea a good one? I really don't know how to do things as someone who's motivated, and retains a lot of knowledge I learnt before my concussion, but struggles to learn new things and stay awake. I'd appreciate some advice.
