pain!!!!!!!

i was walking out of the science building today after class and i slipped on ice and feel right on my knee!!!!!!!!!! i kinda stopped and a woman saw me and asked if i was okay and i nodded and tried ot get up....she said,"no, no....give yourself a minte..." i waited and then tried to get up but the pain was so great and my backpack was so heavy that i couldn't.....the woman helped me up and then said,"why don't you sit down??? og inside the building and sit down..." "no i'm fine.." and i started crying and she said,"are you sure you're okay? try to walk on it..." i did and i limped....she said,"are you SURE you're okay???? you're gonna have a big bruise there....you SURE you're okay???" "yes, yes...thank you.." i limped away crying and then i was driving home and kept crying.....i looked at my knee when i got home...it's purple and red....it looks like the skin has been scraped off my knee....it hurts sooooo much and i used three bandaids to put over the wound....it's bleeding a little bit, but not much....it hurts like hell!!!!!!!!!!!!!
