Please have them get you to a doctor. Also it sounds a lot like
Post Concussion Syndrome. And the main thing that helps with
this is sleep and rest. And taking your time to get back into
your routine.

The thing is you may need some test done to make sure that everything
is okay. And then you might need to have the doctor write a note
explaining about this to the school so they can help adjust your days and
testing especially.
