Hi OPAGirl,
I hope that you check out Alpha Gamma Delta and Sigma Kappa.
There is no harm in having a look and see at their COB functions.
Perhaps you will find your new home in one of those groups?
And if it should be that neither group feels quite right, don't feel that you have to endure the terrible treatment in your current GLO--definitely look into formal recruitment next fall...
But...I have a good feeling about this COB business!

Crossing my fingers for you!
Good Luck!
