I've watched a LOT of House since about my 7th month of pregnancy. In one episode, I actually learned something pretty profound...
In an explanation to his psychologist, House explained that he chose to stay miserable because it seemed 'fair' to him. At some point, he had caused someone pain, and so he had to feel equal pain.
His psychologist said, 'You are not God. Accept the circumstances as they are. Apoligize if you did wrong and then move on."
So...praise the Lord in good times and bad, but most importantly don't try to control something you are not in control of.
