What should i do about my foot/toe blisters?

I got blisters yesterday because i kept money in my shoe because i was at an amusement park and that was the safest place for it. Now i have a blister on the bottom of my foot and 1-3 on my toes. I've been wearing socks and slippers to keep as much pressure off them as possible because i'm limping as is. But i have school monday and i can't go to school with them on my foot (yes i only have it on one for some reason), what am i supposed to do :/ ?
