Transferring to another school so that you can have a chance of joining Z seems like a very drastic step. You would have no assurance that you would be offered a bid there, and you don't know whether you'd fit in better with the members of Z on that campus. I think you're suffering from a case of "the grass is always greener on the other side of the fence syndrome"...instead of fantasizing about how much better it must be in Z sorority, I think you should make every effort to put on a smile, make some friends, and contribute to the sorority you have joined.
