Sorry about your situation, no greek should be that unhappy with the standards of their living arrangments and the behavior of their sisters/brothers. We have a bitch session as well called Roses and Thorns. We start off on a positive note, but it usually ends up with the "thorn" part coming alive. The darn things can last for hours, but sometimes that's just what you need to properly settle things. We always end the session on a good note though (hence the "rose" part).
We had a mandatory Vision Retreat when it seemed our chapter was getting "cliqish" and a little out of hand. Seriously it brought everyone so closer cuz we realized our individual needs and came up with ways to work them our together. You can make these retreats fun by planning teamwork games and bringing lots of snacks, and cameras are always good too.
I hope everything works out for you
