Hi EmptyShell,

Cognitive distortions, dichotomous thinking or black and white thinking can be found in alcoholism, survivors of childhood trauma, depression, NPD / BPD. A sufferer of BPD will take it to the extreme.
It's viewing things unrealistically and can cause us to feel negative emotions, it's seeing things as either all bad or all good and not seeing the space in between, the grey area.
Do you recall experiences where you were put on a pedestal or devalued?
