uwwsweetie,
I agree with TriSigmaPenny, we have all been there. There are ups and downs in Sisterhood, just like there are in any friendship. It takes awhile to adjust to being "completely" in the group after initiation, but things will level out soon. I'm sorry a few women have had such a negative impact. Try to remember not to let them get you down.
~~Sending you happy thoughts~~
Sigma Love and Mine,
ShyViolet
