Is there some type of sign for deep nostalgia?

I long to move back to where I used to live for 6 years. Circumstances that made my life incredible uncomfortable for 2 years ultimately forced me to move out of the state. This was a result of a fight or flight response, and I did not see a way out where I lived. My life became more difficult the past 2 years where I am now, its sort of settled for now. I am not happy where I am living and want to move back to where life/God pushed me from.
