Just off the top of my head---
I don't specifically know about routes you can take if you were initiated and you want to revoke membership. It would be a touchy, touchy subject.
However, there are other options if you were intitiated into a national NPC sorority---
1. a national NPHC (traditionally African-American) group or NALFO (traditionally Latino) group
2. a national mulitcultural sorority (very diverse)
3. a local sorority
4. another national sorority, such as Beta Sigma Phi or SAI
Of course, with these options, it would depend on what you're interested in and in what's available around you. Let us know more about your situation.
This thread would also be more appropriate in another forum perhaps???
