I have encountered this a lot in my life. I have learned boundaries are vital. And realising most people employ a range of cognitive distortions to deal with the worst of suffering in life. It makes it easier to deal with.
But, that never helps complex trauma survivors. It only hurts them more. It invalidates their suffering and creates shame and further isolation, withdrawal. And further pain and suffering.
It is my goal, to do my little part, to educate about this.
And I am educating people about this, including highly trained mental health professionals.
