Shut down, my friend. Shut down. (Thinkstock)

If using Facebook makes you sad, you might get sad from using Facebook.

That's the big, uninteresting result of a study out of the University of Missouri. Researchers from the University's School of Journalism—you thought it would be psychologists, didn't you?—surveyed students at a Midwestern university who used Facebook for two hours a day on average to find out how Facebook made them feel. Shockingly, students who felt "envy" when looking at their friends' pictures and status updates also reported feeling symptoms of depression.
