Really?!?

So i spend my saturday at a swim meet. Which was fine I was doing alright matching my best times and whatnot. So i swim the race im best at (the 500) last, and I was working my but off i ending up getting third against some of the toughest, big, buff girls which i was glad with i worked my butt off. Just to find out im being demoted. A little background, I am/was the best from our town at the swim. And in our big nine i was seated 13th overall with the amazing ladies. But back to the story , I crawl outta the pool to overhear my coach telling another girl on our team that she is going to take my spot as first varsity. Just because the last 2 meets i havent won! I pretty much ran to my other teamates (not wanting to have my friend/new apperentice) see how saddened this made me. I am so disapionted at myself for being jealous and the fact that my coach did that. This girl could swim any event and they chose my race! The race we are doing fine in, getting second thirds and firsts!!! They just had to take this away from me one of the things i was proud to let everyone know, but hey im being demoted b/c i got third. i guess thats not good enough.
