You still have us!
I understand... I think we all go through this with friends and sisters.
Like Winney said, you can always join an Alumnae group... Or heck, plan a bbq or pool party and email everyone, asking them to come. I've noticed that when someone's been gone from a group for awhile, once they take that initial step to go to one event, they're more likely to keep in contact.
If you want to talk, PM me.
