This is a question I ask myself often, and even more so as of late. Recently I read an article on depression that said most people who don't have depression are relatively happy or at least content most of the time. This absolutely blew my mind. That made me think that I've had depression for most of my life, even during my childhood, as I was prone to unprovoked sadness even then. I don't know, it's hard to say looking back as I can't be present and feel how I felt then. Anyone else think about this stuff?
