helloo, pls don't worry too much about feeling out of sorts from uni! it took me a year to feel anything but confusion or like an imposter in my classes, but turned out everyone else felt the same way and all of us were pretending lol. i'm also always falling behind in classes, i swear the amount of reading they set isn't even POSSIBLE with a full workload, so just do what you can -done is better than perfect, health comes first, and teachers, colleagues and uni services can help out a lot if needed 🙏
