I got an academic achievement award, so why am I upset?

This year I got a Social studies award. It is given to the student that has the highest average in Social studies for that team. There are 4 teams in my grade, and about 300 students in my grade. I was pretty proud of the award at first, because I noticed how well I was doing in Social studies. I've gotten straight A+ each marking period, and last marking period my grade was 99.6%. My teacher congratulated me, but when I asked him what I did to get it, he explained that I had the highest average in my team. Great. Then he went on to tell me, that my close friend, who is a complete genius and outshines me in everything, could have gotten a higher average then me, but didn't receive the award because she got a Team Award. Basically instead of just having the highest average in Social Studies, she has the highest average in all her classes, thus she wasn't able to receive my award. I'm not sure if that means she did get a higher average than me, or she could have, but he meant I still would have gotten the award anyway. Either way, it kind of deflated my mood. I love my friend, but it seems like I'm always second to her. I get great grades, just not as great as hers. My one teacher likes me, but adores her. I just feel like I'm like her, but not as good as her, and It does get to me sometimes. Then I finally get an award, and yet I'm told she could have still outdone me. I think what bothered me was that she was the person my teacher used in his "example", if it were any other "nerd" or "smarter person", it probably wouldn't have bothered me as much. I just don't know if I should be proud, or not. I want to be happy . . . it's just hard.
