Re-rushing, what do you think?

Maybe some of you can help me out on this, here is my situation:

I am a junior, and I decided to rush in the spring only to one house because they all had different dates and that was the only one that I knew off. I went there, met the girls, and I felt like I fit in perfectly. They said that they would be calling that same night to let us which got in and which didn't. I got a call later on in the night saying "sorry to inform you but i didn't make it because of my junior standing, and they didn't have enough spots, but she recommended that I rush in the fall because it's alot better and there are way more spots. Well, after a few months, I e-mailed the same girl who also happens to be the VP of recruitment asking her if she really thinks I have a better shot in the fall, she never replied. Now, I am debating if I should rush again in the fall, it's about 20 days away from fall rush, and I don't know what to do. I don't want to go through the same thing and not make it and be upset for days like I was last time, and I feel a little embarrased to go to the same house again, knowing that all the girls know that I am rerushing. I don't know what to do, I feel like I'm so close to the end of college and I haven't enjoyed it and feel like a sorority might be the best thing for me. One of the girls who also rushed with me in the spring, who also happens to be a junior, was called a few days later after bid day saying " a spot opened" and she got in, me and her are no longer friends" has nothing to do with this" but also I don't want her to say something that will make that sorority not want to invite me back to the house. Any help??

thanks
