My Secret Weapon Against Depression | Psychology Today:

After years of therapy, I’ve learned an invaluable lesson: know your
enemy. When I can’t move, when it hurts to blink, when my body
protests against every breath, I know who’s come to visit. When I get
global – nothing is good, everything is awful, the whole world is
against me – I know what’s going on. The smartest thing I can say to
myself is, “It’s depression talking.”
