Difficulties in leaving

When you have a chance to leave where you are in life right now, there are always difficulties. Some are difficulties in the move itself; you have to pack things down, get them transport, unpack them. Finding a place can be difficult as well.
Sometimes it isn't what you are taking with you that causes a problem, but what you are leaving behind. In my example, I left behind a well paid job to come to the Faroe Islands. Now I am in a difficult situation; I can have that job back, but I need to leave my kids up here. Easy choice for most, but not when you are looking at a budget breakdown. I am broke, so how the hell do I pay for anything at all? It wasn't pain free leaving Coop; I had a lot of friends there. I also had no job coming up here and entered an uncertain situation.
Using that as a reference point, leaving kids behind, to a certain economic situation and stable daily routines is a hell of a lot more painful. It isn't a choice I feel I have. I feel like this is something I am being forced into by my low income.
I don't know what I should do here.
