I had severe borderline personality disorder in my teens and early 20s, under right psychiatrist I completely recovered didn't qualify for the diagnose anymore . I then went on to be diagnosed with borderline personality disorder again in my forties from having very bad PTSD . I'm just wondering has anyone been diagnose with borderline personality disorder in their youth , gone in remission for about twenty year's only to get the whole disorder back again in your forties .?? needing the mental health symptom again . I'm always reading that people get fewer or if any symptoms of bpd in their 40s and 50s and I haven't found that to be true to me .
