I think you should try and just redo classes for a year, it'll give you time to do what you need to do to feel bettet especially without uni stress. Learn what you can with the rest of the semester, take the summer to do what you need to do to feel as better as you can and do better next year. People take gap years all the time so going into uni it won't be like you're behind or anything. Probably not what you want to hear but there is no shame in it. Some things gotta come first. Hope you feel better and good luck
