Now i know why you are depressed: you are on facebook!
Before memo, Yours, and so forth, there were no social networks that did nearly half the job of fb in terms of being able to interact with others. I was depressed long before fb.
You know what - sure, it's facebook. I mean why not. You want to just narrow it down to one thing, go for it. Also, meditation and no weed. Binary thinking ftw.
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.
I would appreciate if you considered that what benefits you might not be what someone else needs. What you're saying has general benefits that I agree with though.
You are totally overanalyzing what I said. I was just talking about my own experience. To find out if that can help you is your own responsibility I do not even think about that.
