" In Man’s Search for Meaning, Victor Frankl points out that while we cannot escape suffering, we can change our attitude toward it. We can regard it as a necessary part of life, even as a great teacher about life. If we substitute “pain” for “suffering,” I agree with him. A great deal about life—wounds, hunger, old age, loss of love, loss of loved ones—hurts. Pain really is bound up with the experience of life. Suffering is not. I find it useful to think of suffering as our resistance to pain. We can even quantify this in a crude way: pain times resistance equals suffering. The greatest pain I ever felt, my mother’s death, became bearable to me because I accepted that she had grown tired of life and needed to move on. I wanted her to find peace much more than I needed a kind ear to listen to my problems.
Whereas other pains, seemingly of much lesser degree, such as that of my girlfriend casting me aside at a time when I most needed her, I resisted with each stubborn breath and agonized thought of her finding some wealthy guy to love and to hold in replacement of me. And so I multiplied a lesser loss into an intense longing and burning for what I could not have, and therefore I created for myself a sheer, living hell. "
