Although I have not experienced anything even remotely as horrible as what the author has, I can still relate to this. I've been exposed to enough frustration and injustice over long enough periods of time that I can't cry about anything anymore. Last time I cried, I must have run out of tears mid-way through because I actually started chuckling at my own misfortune. I guess maybe my problems are in fact trivial in the grand scheme of things.
