But sadness can give way to depression when the sadness turns into endemically harsh negative thoughts and feelings. This morass of negative thinking then generates tension, aches, pains, fatigue, and turmoil. These, in turn, feed more negative thinking; the depression gets worse and worse and, with it, the hurt. We only compound our feelings of depletion if we deal with them by giving up activities that normally nourish us, like getting together with friends and family who might be a real support for us. Our exhaustion is compounded if we deal with it by simply working harder.
