Is my toe sprained or broke? ?

We had a party out at the college nd someone decided to trow me in without letting me know... My left foot caught the lip of the pool. It turned red nd started swelling couldn't walk on it. I hung out with my friends awhile longer nd when leaving it hurt bad. Now its badly bruised very swolen. Can move but barely... Its tilted over like sideays slightly. What do I do. A friend said I should put heat on it and another she said ice. What's its problen? Broke or sprained
