" Everything turns inward in depression. A beautiful flower momentarily catches your attention, but within seconds the focus bends back into your own misery. You see loved ones who are celebrating a recent blessing, but before you can synchronize your feelings with theirs, you have doubled back to your own personal emptiness. Like a boomerang that always returns, no matter how hard you try, you can’t get away from yourself. "

― Edward T. Welch , Depression: A Stubborn Darkness–Light for the Path
