Suffering from depression, I can honestly say that it's not always a choice. Sometimes I can talk myself up, motivate myself, say there's world's great, my life is great, and be kind and nice to everyone in it.
But somedays, I can't get out of bed because there doesn't seem to be a point. I can't move or eat or do much of anything, besides lay there and think of how bad things can be or have been. A person with depression cannot talk themselves out of it, like people think. It's not so simple.
Sometimes I wish the world would understand, when I'm having a day like that...
So there's something to consider the next time you feel that a person you're speaking with isn't going entirely out of there way to make you feel better.
