Do you have the option of starting a new sorority on campus?
Is there any school that you want to transfer to?
These are two backdoor ways that you can become Greek.
If you never make it, here's a way to look at things...
Counseling won't make you feel better, lol. Filling that void, will. Think of filling the voids (whatever they are) as an end, think of sorority life as a mean. It is a great mean, but not the only mean. There are other ways to keep your self happy during and after college, but you will have to search for it. I eventually did after dropping out. There's light at the end of the tunnel.
