Katey, have you thought about assisting the New Member Educator? Even if that isn't an official title, I know that the pledge moms need all the help they can get! That is an excellent way to get to know the new members.
Also, if your sisters have joined a Junior Circle, there's nothing to stop you from attending their social functions. Its a great way to keep in touch with your sisters that have graduated. Goodness knows, we younger alumnae miss our chapters and we love to see our undergraduate sisters!
And Katey, when you feel that you're not a part of the chapter, just remember that you are a part of a giant international organization. All of us Alpha Gams here on GC love you to death! You'll always be a very important part of THIS chapter.
LIEP,
GLG
