Of course, in your case, if you relax, you'd better drop out of school next time, and you won't be too tired.
But you only have a broken foot and no head injury. In addition, you can't run around after you break your foot. You can borrow your classmates' notes, get a recording pen to record the teacher's class at home, or simply teach yourself. As long as you can keep up with the progress, you should have no problem going to the original class.
I've been suspended twice, both demoted. It's really not cool, but I can't teach myself because of mental problems, but you are different.
