School guidance... help please!?

I attend a high school in Toronto , I'm a sophomore.. I realized I worked and learned much better by myself so I'm considering taking online school courses for the next 2 years plus I have medical issues that cause me to miss school occasionally and it would be much easier for me. But my school has a very strong Arts program (the best in our district school board), I love acting and I'm determined to become an actress; in grade 11 they have a special 2-credit interdisciplinary program that gives me a GREAT opportunity.. I took the Acting for TV & Film course last semester and LOVED it next year the course requires you to attend casting calls, start up on acting resumes and job shadow professional artists ect. I REALLY would like to take this course but Math is also stressing me out A LOT, I ALWAYS hated Math and I can't stand.. my school board requires 3 math credits for you to graduate but I can't take one more day of it!! I know basic math and math useful for workplace but I don't need all this extra complicated math to become an actress.. is there anything I can do?? This is driving me crazyyy.. I'm constantly worrying about failing Math and I have enough on my plate already.. PLEASE HELP :(
