Feeling really down about myself...why didn't I get asked back by any sororities?

[RKelly74]

I decided to rush as a sophomore at University of Michigan because I was just too overwhelmed to do so freshman year. I just got through the mixers, which is the first part where we go to all 15 houses and talk to about 3 girls in each house. Then we rank the sororities for the first time and get asked back for "second sets." I didn't even make it to this because I only got asked backed by one sorority to even go through second sets (after this, we have third sets, then preference parties). I didn't feel like I fit in at all with the girls I met at that sorority, so I am now just dropping out. I don't understand what I did wrong. Most girls get asked back by up to 11 of the houses for second sets. I dressed nicely and was very polite to every girl I met. Freshman year, I met a popular guy in phi psi (the "top" frat at out school) who had a crush on me, and he said to definitely rush as a sophomore because he thought I would get a top house, which in his mind is Tri-Delt (I guess because he thought I was attractive). My rho omega said she couldn't tell me why the sororities decide who to invite back, but she said it could possibly be because I'm a sophomore. However, I had a friend rush with me who was a sophomore and she got asked back to 11 houses, including Tri Delt. And a lot of the girls who even rushed me told me they rushed as sophomores. My GPA was not the best freshman year, but it wasn't horrible either, and the sorority girls I talked to said they don't look at the academics that much; it's mostly about the friendships you make. There seemed to be hundred of girls rushing, so I don't know how the sororities could even know me or remember me enough to reject me at this point. I saw some girls that I knew from freshman year rushing the new potential members, so do you think if a couple girls didn't like me or something they told the rest of the sororities? What went wrong? Maybe I talked about something I shouldn't have during our conversations? I live in an apartment with 3 girls in ADpi, and I had a cousin who just graduated from here in alpha phi, but I of course didn't get asked back to those sororities either. I was so excited to rush, and now I just feel horrible about myself.
