UNC12, I really do sympathize with your situation, but realistically joining another group is extremely difficult, and may not even be possible depending on the organizational policies of the groups on your current campus. (For example, some organizations will refuse to let you resign your membership, other organizations will not initiate you even if you have been able to do so.)

You need to contact your chapter of initiation to verify your membership status, as long as you left in good standing you are probably considered an alumnus by your HQ (DISCLAIMER: I don't know what your fraternity's policies on the issue are, which is why you need to check!). Start looking at ways to make an meaningful impact as an alumnus, because, in all likelihood, it is probably the best chance you have.
