From my observations during life I say that the circumstances make people depressed. Family can be a curse even if perceived differently because of fear of the unknown.
That might sound odd to you. I also think it's odd to specify only fb. We are social creatures. Aside from online right now, I'm pretty much isolated. It's a complex situation.
Not that complex situations can't have simple solutions. I think your way of going about solving for my is overly simplistic, especially since you don't gave the contextual data.
