Sam,

You would be eligible for temporary accommodations and/or modifications depending on your individual situation and individual needs. You should ask your parents to look into that before your return. Any school staff who have contact with you should be informed about your condition and educated about that condition AND your specific symptoms/needs.

This is a PDF file and outlines steps that need to be done. It also outlines formal support services such as IEP which is an Individualized Education Plan, or a Section 504 if temporary accommodations are not enough and your symptoms take longer to resolve than at first expected.
