I Just Don't Get It...

So. We just had elections for next year for my sorority and I ran for president. I found out today I didn't get it because many think I'm an airhead ditz who doesn't take anything seriously. Seems like they don't know me at all and it really is heartbreaking. This past year I had already been doing half of the president's duties, was on student senate and started the nursing program at my school a semester early so now I'll be completing school in 3 1/2 years instead of 4. How has all of this gone unnoticed??? I don't understand how the majority of my sisters could possibly think I am incapable of running our meetings (seems like that's the one duty of the pres that I wasn't doing). I know I made a couple mistakes my first semester in it, which happens with everyone at least once and have held this against me for the past year and a half. Now, they elected a shy girl, who doesn't really socialize with anyone outside of our sorority. So I just don't get it... I know I may be goofy and make jokes but that's my personality and here I thought we accepted everyone as they are since that's what we always say. But as every other position was elected few actually spoke their opinions and the majority followed those few. So it's just disappointing that people who I thought knew me and that I could trust that now I feel like I really can't at all. I shouldn't feel like I have to prove myself to them after all I have done.
