Honestly?

At this point, I think you would be better off to cross your mom's sorority off your list*, wipe them and everything you know about them from your mind, and if other sororities ask why you are rushing as a sophomore/re-rushing, say "I foolishly put my mother's desires ahead of my own and didn't really take a good look at all the groups. I'm going through again because I want to remedy that." I have the feeling that if your mom is doing things like calling the GL office, people already know who you are (and probably feel sorry for you at this point) and which group your mom is an alumna of.

*This does not mean be rude or dismissive to them at the first round of parties. Be polite, but don't gush or beg. Even if you would get a bid there this time around, it's more than likely that your time as a sister would be filled with drama and your mother's interference.
