Diagnostic overshadowing is when physical health problems, pain, or not yet diagnosed health conditions are not taken seriously, or are seen as delusional, attention-seeking, or made up because someone has a mental health diagnosis and/or self-injury scarring.
*Invalidation
Invalidating someone else is not merely disagreeing with something that the other person said.
It is a process in which individuals communicate to the other that the opinions and emotions of the target invalid, irrational, selfish, uncaring, stupid, most likely insane, and wrong, wrong, wrong.
Invalidators let it be known directly that their target’s views and feelings, do not count for anything to anybody at any time or in any way.
