I think the BPD label can be harmful, because it comes with too many preconceived notions (that bpd is hard to treat, that patients are hopeless cases etc.)

My T put it brilliantly years ago--- "BPD is what they call you when your clinician doesn't like you." as in, it can be a dumping-ground diagnosis.

You can be helped!! You are worth helping! You are not an awful person!
