injury help? what should i do?

[Puppy lover]

Okay so im gonna try to make my long story short. So after a volleyball game, me and my friends went to souplantation. I went without my shoes cause it was about....95 degrees hott outside and left it in her moms car. So we just found out she left us there and our high school is like 5 min away so we started walking up a maybe 2 mile up hill barefoot. So etc etc etc. blah blah. So i ended up getting a maybe dollar coin size blister. It ripped later which hurt sooooo bad. Then just today, i was in dace class and i had to do turns on the ripped blister bare foot on hard waxed floor.....OUCH! it turns out i ripped it even more to the side so i cant walk on it at all. What should i do? i wrapped it up but still hurts.
also i have volleyball and dance everyday so i dont know how long the process will like resolve. I have to dance barefoot everyday and i have to do volleyball etc. on wood floor so i dont know if it will keep tearing and ripping or not.
