Performance tomorrow twisted ankle help!?

ok so i know that I shouldn't do anything on a twisted ankle for fear of making it worse but I have a dance performance tomorrow (dancers know how it is...MANDATORY) and I'm pretty sure i twisted my ankle learning a lyrical dance for the performance tomorrow, there is a lyrical routine with lots of leaps and jumps and a hip hop routine as well... I don't want anyone telling me not to dance tomorrow because if I want to make the high school dance team, well, I have to. I know i should stay off it as much as possible as I can barely walk and I have been icing it and all i have it elevated at the moment and I'm going to soak it in epsom salt right now. I'm thinking of wearing an ace bandage tomorrow. My performance is at 10:40 AM PST and I need a quick way to lessen the pain alongside the ibuprofen I've taken. Please help me I really want to make this team!
