One of the things I enjoy doing is watching birds. They live fiercly. Take robins, for instance, that anyone can watch who live in North America. They stake out their territory for their mate, nest, and raise their young. They chase off curious predators. They go from plump to skinny as they give their all to the nestlings, worm after worm. As the fledgling jumps the nest, they hover, quietly nearby, protecting them as they learn to fly.
If they fail, and this happens often, they start again. They may nest three times in our short summer in the hopes that one will survive.
As an aside, I cringe when the WTS speaks of "coping". Life cannot be contained in such a small word. Life is to be grabbed with both hands.
You can come back and read this later, when your depression lifts. I know this is hard to imagine right now.
