There's so much for me to be thankful for a lot. I have my health, at least I don't feel like there's anything wrong. I have shelter; out from the cold, enough money in my savings, a job I like with nice people, car running good, and other things.
I think that with depression, it seems much easier to dwell on what's wrong rather than what's right. In essence, at least that's how it is for me, there are more items in my life that are right than wrong. But I make the mistake of thinking about the items that are wrong.
Every night I thank the Lord for all the good things He's done. It really makes me feel pretty good before going to bed.
