First off, it's a given that things won't always go the way I want them to. Duh. I'm not the Sovereign Lord of the universe, so it's just basic theology. I'm free to long, struggle, and mourn, but it's foolishness bordering on arrogance to be shocked and indignant when I don't get my way.
And secondly, yes, we can stand it. At least most of us can, most of the time. There are exceptions, of course, but come on. The tsunami disaster is a good example for perspective. Has my home, community, livelihood, family been wiped out? Do I face carnage whenever my eyes are open, and images of it whenever they are closed? Have I bled? Have I lost a limb? Am I at a loss as to where my next meal or drink of water may come from? Maybe it's worth considering that I'm blessed, even if I suffer some of the inconveniences I face. Maybe I don't truly know suffering at all. Maybe my license to bitch, externally or internally, has been revoked.
I don't think any of us has to deny our pain. That's stoicism, not faith. Those who follow Jesus have been freed to struggle, and struggle honestly. I do, however, think many of us push away the comfort the Holy Spirit offers us, because that comfort requires that I acknowledge that He is God and I am not, that I don't always get my way.
God is sovereign and He is good. The fact that He is sovereign means He rules the universe and I do not. The fact that He is good means that His rule is better than mine, both universally and in the intimate details of my life. In every way I deny or rebel against that, I'm walking in darkness, in death. Submitting to Jesus is embracing a hope far greater than getting my way.
