Generally people with BPD get labelled as hard to treat, or just being manipulative. Having BPD shouldn't affect treatment, but unfortunately it does. I recently joined a
facebook group who are campaigning for people with BPD (and other mental health conditions) to get listened to after recently some people with BPD were turned away from hospital and killed themselves. There's going to be a protest in London next week about this.
Although, personally, I've never had any trouble being admitted to a psych ward.
