And a large percentage of therapists would agree with you. Trauma is the basis of many "disorders", but especially BPD. And yes, diagnoses can be highly stigmatizing and even counter-productive. Not all clinicians see the DSM as the holy grail. Some of us even think it's only reason for existing is to provide a means to monetize mental health (i.e., bill insurance). Here in Portland, many counselors and social workers are willing to see past such labels and connect with you as a human to provide the support you need and help chart a path forward. Finding the right therapist takes time and effort. Please don't give up just because of a few bad experiences. It's the quality of the relationship that does the helping, not the initials after someone's name. Or the diagnosis that they give you. Therapy can work, if you are humble enough to accept the slow progress that comes from being seen, heard, and cared for week after week after week. Once that stable, trusting base is there you might find yourself finding creative means of applying the concepts discussed to your own life, rather than "outsmarting" your therapist and shooting down the profession as a whole.
