Not so. Certainly in many contexts it is a clue that reframing the problem might be useful but you certainly don't need to. In many cases doing so might even be counterproductive. There are times when being frustrated or even angry at the situation you find yourself in is the right thing.

I'm not saying that's necessarily the case here. Just observing that frustration doesn't necessarily imply that you're wrong. Of course the inverse is also true. Being frustrated doesn't mean others are necessarily in the wrong - it might well be your own damn fault.
