A job in health or social care will help thicken the blood. One dark grim crisis to another, looking for the best outcome while another dark grim crisis unfolds. Gallows humour or go insane.

And in personal disasters, loss of loved ones, there is a craving for a return to normality, like begging the world for everything to be okay again.

If your story is full of misery and challenges, your characters will have to have a method of coping with that misery and rising to those challenges or they won't survive them. Not without sneaky help from the author and most readers will notice that.
