Please Help! I just have questions...

A NOT hypothetical situation, but I'll use cheesy Greek code to explain what is going on here:

I attend Cyprus Rhodes University and just went through Formal Recruitment. At the end of Pref Night I listed my choices putting ZBZ first, Tri Pi second, and IKI third. I was fairly certain I would get a bid from ZBZ the next morning, as both girls I talked to said "they could really see me there." But, I got a bid from Tri Pi.
Of course I was upset but I went to the Bid Day party. And I really didn't like it. I didn't fit in with my Pledge Class and I was SO not excited to go back for my first new member meeting. I decided to give it a week, so I did, and I still don't like it very much. It's just not the place for me. But I know that ZBZ is!
I have my Pledging-In ceremony THIS Friday and of course want to make my decision to drop out or not before then. I don't know what to do! I can't imagine NOT being Greek after I have wanted to for so long, but I definitely know this is not the place for me to do so.
I also know that after signing my Preference List I am bound to a sorority for a full year before I can rush again. BUT, one of the sororities on my Pref Night list was all it said. So does ZBZ technically count? They have snapped maybe like 1 or 2 girls since Bid Day in...could I work my way in w/o getting in trouble with NPC? I am DESPERATE here, let me know any loopholes I can work with! (And suggestions on how to get snapped in/ informally be recruited in--since that is going on right now!)

THANK YOUUUUU!
