It is indeed true Borderline Personality Disorder may be treated and symptoms can be addressed with medication and therapies like DBT or MBT. I suppose a good way to understand it would be to say that the disorder may be brought into remission. If however underlying causes are not addressed symptoms may be triggered. A great failing with treatment is exposure to stressors. It is difficult for example to teach someone that their feelings are real and valid should someone else be undermining that. It can be difficult to teach someone how to properly manage their impulses and think through their actions should those around them dismiss their ability to do so. As I have explained, this is where a good support system enables recovery.
Again, how are people supposed to access these therapies?
I have sobbed in GP's surgeries only to be told there is nothing they can do because the 'patient' has to seek therapy themselves. I'm the one who gets offered the counselling and group therapy, yet I am not allowed to mention that the stress I am under is caused by someone else.
It's a crazy circus because what you seem to be saying is that mental health issues can be caused by someone else?
How do you 'teach' someone that their feelings are real?
Teaching is active, not passive.
Who might the mysterious 'others' be that are undermining someone's real feelings?
Are you referring to gaslighting here?
Can managing impulses be taught? How do people access this education?
Again, you refer to people 'around them'- who are these people- family, carers, friends, therapists?
I wish I knew where these good support systems were, because I haven't come across any... and not for the want of trying.
