Need some help...

Okay, so here's my story. I just transferred to a new school in the Fall of 2009 and knew that I wanted to join a sorority. In the beginning of the semester my school had a fair with all the organizations present and I ended up talking to two sororities: Alpha Gamma Delta and a multicultural one. At that point because I didn't know anyone at the school I didn't know which one I was more interested in so I figured I would go to the rush events and see where I stood from there. Alpha Gamma Delta's events were like 3 weeks before the other sorority's events so I went to like 3 out of the 5 and ended up getting a bid. Yay me! The night I received my bid(Friday) we were informed that x-amount of money was due on Wednesday. I was like damn well that was a waste of time then because I am unemployed due to just moving to the area and not having parents to support me financially. (I know there is fees/dues/etc when involved in a sorority but I didn't think it would be due that soon) But then they informed us they'd work with us with with us in getting the money if we don't have it so I ended up accepting my bid. About a week later I get an email from one of the sisters with a list of other fees associated with the sorority thats now due. Once again I'm told they'll work with me to get them paid, especially because they knew I was waiting on a refund from the school which I planned on using to pay all my fees. At this point I'm still going through pledging and during our weekly "classes" we're given assignments to have "dates" with different sisters and every time that I try to contact someone I either a)get ignored or b)they're too busy to get together, this includes my sister mother. Then I ended up staying home from class one night because I didn't feel good, text my sister mother(since she's the only ones number I had) and asked her to let them know. A few days later I see one of the sisters and she gets an attitude with me saying "next time you're going to miss a class let someone know because we waited for like 15 minutes for you" and I explained the situation. As time went on I started to question whether or not Alpha Gamma Delta was the right sorority for me but continued to go through the process because I really did like a lot of the girls(especially the other pledges). About a month before initiation we had our regular weekly meeting when the sister, who told me she would work with me to get the money, and my sister mother pulled me aside and told me that if I didn't have all the money in 2 days that I could no longer continue with the process. Obviously I don't have the money and was unable to be initiated. So now, I am a little upset by this because if I would've realized that it wasn't going to be worked out realistically I would've never wasted their time or mine attending the meetings, classes, bid day, etc. and waited to do the sorority thing. They suggested to me to wait until the Spring semester to pledge but honestly I don't know if I really want to any more. Maybe it's just me being paranoid but I think that because I didn't finish the first time around, it'll be held against me.

Then I still keep thinking about that other sorority. So my questions are:
1.) Am I eligible to rush/pledge the other sorority even after accepting a bid to AGD?
2.) Would it be better to inform them of my situation with AGD ahead of time so it's not like I'm "hiding" anything?
3.) Do any of you have any other advice about this situation?
