What's wrong with me?!

You see I am a freshman and I do track. I was the only girl in my school in 1a to make it to state track championships.. I qualified for the 3200m and 1600m.. so I raced and got 11 in the 2 mile and 12 in the mile.. I wasn't proud if myself.. Like I wasn't even happy to be there. Is there something wrong with me? Why did I feel that way? I was the only freshman girl And girl at that to go to state .. I was with all the boys.. Ugh why wasn't I proud of myself??!! Help please... :'(
