Katie,I am sorry to read of your problems and wish I could advise you wisely. However, I cannot tell you what your problem is nor can I recommend whether or not being home-schooled is a good idea for you.
I would suggest your parents contact the school nurse and discuss the nurse's assessments when you have gone to the health office at school.
Wishing you the best and do let us know how things are going for you.
Kindly,
Kitt
