the word of truth

I've been looking for something to cheer me up. There's no point in telling a depressive mind to think happy thoughts.
I think that's maybe one reason why the bible is good for depressives. Because it's kind of not necessarily that happy. You know even though I think I'm a Christian, if I'm in a dark place...Christianity is as annoying to me as it is to everyone else. I have a keyring that says 'Jesus loves you,' and if I'm sad that statement of true fact can be a major encouragement - but if I'm depressed, I could just as easily throw it out of the window.

So I was wondering what is the difference between depression and sadness. Then I read James and the first bit blew me away.

At the center of my worries and anxieties, is pride and at the bottom of my depression is doubt.

James 1: 5 If any of you lacks wisdom, you should ask God, who gives generously to all without finding fault, and it will be given to you. 6 But when you ask, you must believe and not doubt, because the one who doubts is like a wave of the sea, blown and tossed by the wind. 7 That person should not expect to receive anything from the Lord. 8 Such a person is double-minded and unstable in all they do.
