Does anything in nature despair except man? An animal with a foot caught in a trap does not seem to despair. It is too busy trying to survive. It is all closed in, to a kind of still, intense waiting. Is this a key?
Keep busy with survival. Imitate the trees. Learn to lose in order to recover, and remember that nothing stays the same for long, not even pain, psychic pain. Sit it out. Let it all pass. Let it go...
Letting things happen naturally is terribly difficult, almost ridiculously difficult, but it’s the only way. I used to worry too much in the past, it seemed I couldn’t let go of what was destined to be lost – …like holding a kitten too tightly or a flower that wilts if gripped too firmly” .
May Sarton, Journal of a Solitude

Amen to this.
It reminds of what UG said:
“Life has to be described in pure and simple physical and physiological terms. It must be demystified and depsychologised”
