mixed emotions

I got my ticket for my return flight yesterday and now I'm freaking out about leaving.
On the one hand I'm so ready to leave; I don't want to spend another summer melting away here, and I'm tired of living soooo far away from my friends and family, and my job is very unfulfilling.
But on the other hand I'm not ready to leave. I guess part of that is because I doubt if I'll ever come back and I will miss so many things about living here (the food, my maid, random elephant sightings, to name a few), and there are so many other places I'd love to see in India. It is just so far away from the US and an expensive flight, and there are so many other places in the world I want to visit that a return just isn't likely.
Although if you had told me even 1 minute before I was offered the job here that I would live in India I wouldn't have believed you so really it is entirely possible that I will come here again.
For now I'm trying to live up every single moment until I leave to pack in as much of India as I can.
