it's stupid copypasta, but you're not understanding it. it's speaking against the tendency of (especially non-mentally ill) people to downplay legitimate medical diagnoses as "labels." this is a thing I see a lot in twee self-help articles or posted on FB by the kind of people who think essential oils have medical worth - like putting a label on yourself is somehow keeping you from freeing yourself of whatever it is that must be "causing" your mental illness. it has nothing to do with self-dx.
