I would make sure to tell the doctor who prescribed the anxiety medication this particular problem and how it is going to affect you this year at school.

I would also confide in the teacher you are to have for this subject.

Exposure helps to relieve anxiety. You can resolve to commit to this class and ask the teacher to work with you to help you successfully get through the school year.

Confide in your parents. They deserve a chance to comfort you. If they cannot comfort you, they still need to know because they are legally responsible for you. Courage! You can do this.

I have fainted and as you can see, I woke back up. I can look back on my younger self and realize now that I was among a lot of other younger people; all of us trying to grow up and find our way. They can empathize with you if you faint. Anyone who would make fun of you is a sad soul who needs the teacher to instruct and correct them and you to pity them. Courage!
