My perspective...
I was relieved when I had a diagnosis (on a different axis) that explained why I was suffering and gave hope that there were tools to ease or stop my suffering. I had been invalidated by others for my behaviors, which is isolating, so connecting with others who have the same issues is mutually validating and decreases isolation. I can see how that could seem to be glorifying the diagnosis, especially if one rejects it.
Psychiatry and psychology are controlling. Like traditional medicine, they attempt to identify an issue by listing a group of presentations, of symptoms, and then label it. They pathologize behaviors without organic causes, which seem to be responses to pathological conditions, that is, coping traits that developed from long-term unreasonable situations that could not be coped with reasonably.
The labels are damning, such as BPD and other labels on the same axis, an axis that says the issue is is difficult if not impossible to treat, and implies that the person is difficult, if not impossible to treat. Minimizing, invalidating, and isolating a person makes them more controllable. Each axis isolates a group, each more "hopeless" and isolating than the next. Neither psychiatry nor psychology gives a solution to the label, yet they insist they have power over the person by creating the label and getting the person to agree it is valid, sometimes even enforcing them to comply even if they do not by saying the diagnosis indicates one does not have the capacity to agree or disagree.
I eventually stopped believing in and rejected psychiatry, the labels, the axes, and the control. I invalidated psychiatry and psychology, their authority over me, and their ability to control me....as long as I am not in their domains; a failed cbt attempt could put me in one, which makes them judicial, and it's frightening that they have such power. Suicide is a reasonable response to the unbearable and the hopeless, it is not a symptom in a pahology, it indicates a human capacity to solve problems.
That's what I think, for now.
