The tendency for most of us is to strive towards some sort of "dream goal." Many Americans, in particular, were raised with an ideal vision that included a steady job, a house, a nice car, a spouse, some kids and perhaps an animal companion or two. While that may work on paper or may even be an ideal worth striving for it isn't the ONLY way to live. The current state of the world is "constant flux" and it can be a wonderful, freeing thing to examine your ideals and find out what you really want out of life, even if you decide it really is a "white picket fence."
Similarly you might be comparing yourself to your peers--so-and-so may have the biggest TV/car/whatever on the block and you might find your self-esteem slipping when you compare what you "have" to your neighbor. This thinking, although human and "normal," is completely unnecessary...you have what you "need" as long as you truly have yourself.
Consider downsizing...consider re-locating. Traditionally, in times of depression families had to pick up and move to wherever the work was, and with outsourcing becoming more of a fact of life every day it's a good idea to embrace the idea of being mobile--remember that wherever YOU are is, ultimately, home.
If you absolutely can't relocate think about ways you can change your lifestyle to keep up what you have. Maybe you or someone in your family arrangement has to "take up the slack" by getting another job? Maybe someone has to sacrifice something for the greater good? Again, it requires sitting down and looking the "monster" in the eye and assessing what you can do something about and what you can't. You may be surprised how easy it is to change things in your lifestyle once you've set your mind to it and accept the idea that change is inevitable. By embracing this concept and welcoming changes you might even get to a place that is better than where you were originally.
