Sounds like you have done very well, and I think you will continue to do so, even with the bumps that happen in everyone's life. The first time you move away from home, family, friends is extremely hard, it just is. It will take some time to get past feeling homesick, and to make a new place feel like home, so what you are feeling is very normal.

Other than being homesick, were you happy living there before the job mess? If so, and if it were me (and I'm not saying you should do this), I would go back and give it six months before making a final decision about moving back.
