What would you do?

ok so this is my first entry and i just want to know what would you do if you had all A’s in school the past few years but this year, your grades are going down, to like 40’s. so say after all that you got into student council, and national beta club, then you ran for vice president for the student council. but you’re having second thoughts about everything because of your grades your family and everything else? what would you do?
