Viktor Frankl, a concentration camp survivor, would agree with your last point. He wrote Man's Search for Meaning, and one of his main points is that sometimes you can't control what happens in life, only how you choose to act while enduring it.

It's a pretty amazing book. And really brings things into sharp contrast. You might be struggling with work (and I've been in that struggle myself, it's not fun, and hard to escape from), but this man managed to to make it through one of the worst atrocities ever committed against fellow humans, and not fall to pieces as a result of it.
