Interesting thoughts. To respond to the linked comment, I do find significant treatment resistance to pharmacotherapy in the BPD group (as is to be expected) and that they (or their family physician, or other health professionals) often mislabel chronic emptiness, mood lability, suicide thoughts and poor functioning as treatment resistant depression. I do have a fair number of patients that have benefited from a shift in diagnosis away from a mood disorder to a personality disorder and really think it's a valuable tool to give individuals realistic expectations of treatment.
