Far out!!! Why do I have to be such a Klutz!!!

See what happed was today at school, we were doing PE the period before lunch and we were playing Oz tag. I got the ball for the first time and started running... But someone got my tag so i tried to stop running really fast...
And my knee kinda (well it all happened so quickly that i don't excatly know what happened) well it kinda went mbele wrong au something like that (The teacher was telling me this because she was a few metre's away and saw it all happen)
So i was on the ground in a lot of pain, trying very hard not to cry infront of the whole class. The teacher was inayofuata to me trying to calm me down and all that.
And then when she decided to songesha me off the field, she got 2 guys to help me up, and after i got up i was seeing if i could walk and i fainted (first time every)
I came consious about 10 sekunde later on the ground, very confused.
