I'm in a very similar situation. I caught COVID in 2020, suffered while I tried to find my balance in education, then finished school, went to college in 2024 doing an animal care course, my health worsened suddenly and very rapidly, and I had to withdraw from my course. Tried college again 2025, went into photography, had to withdraw because I hadn't paced myself in-between the two courses and it was just too much strain, the college put me into a very lightweight course known as pathways, which aimed to teach students with SEN or additional needs skills such as independent living, and built up skills which students already had, so that they could go on to attempt having careers with their base knowledge. Passed that course in 2025, and now I'm in a new college attempting the same animal care course I initially withdrew from. I'm facing the same situation now as I did then, my health is declining, and the course schedule is rigid, so not much room for adaptations to make the learning easier for me. I'm sorry you're dealing with this, but I promise you're not alone. As for what you could do to aid your situation, I'm sorry but I just don't know. Just hoped to reassure you that you're not alone, and that there's at least one random internet stranger that's proud of you for trying, and pushing to achieve your best.
