When I am deeply depressed, and if I am criticized, I tend toward a cross between 'whatever' & 'add it to the pile' of what's wrong in general.
It comes from that feeling of being misunderstood, not guilt. No one can really know how you feel, and criticism is just pointing out the obvious flaws I am well aware of.(thanks for that...)
Anyone foolish enough to criticize an already depleted person get put in a category of someone to be wary of in future, for me.

And I don't engage. I retreat. No energy for the likes of that. At that point I am barely hanging on as it is...why stand for someone pushing my head under?
