This doesn't particularly surprise me. Facebook is a self-advertising platform; people present a whitewashed and happier-than-reality version of themselves, and when you compare that to your own life (with its problems and warts and whatnot), you might conclude that your life is deficient. It's the "keeping up with the Joneses" problem, except massively amplified.
