hi. i don't suffer from a personality disorder, but i'm very very very close to two borderline friends.
sometimes i can't draw a line that separates their personality traits from the disorder symptoms. that is, unfortunately, true.
but after they started therapy (specifically CBT and/or DBT) their symptoms started to vanish.
having a personality disorder isn't about your entire personality being fucked up. is about having a disorder that can mess up with your personality traits. CBT and DBT are ASTONISHING EFFICIENT on trating personality disorder patients (DBT is perfect for borderline). patients can literally get into a remission point that they literally don't fit the diagnostic criteria anymore.
examples of what CBT/DBT can do for you:
you'll learn to recognize dysfunctional thoughts, automatic thoughts, cognitive dysfunctions, ex: "everything or nothing, when you assume two different categories for people and situations", or maybe "i'm worthless" "i'm useless" "there is no solution to my problem" etc
you'll learn emotional regulation methods and alternative answers to these cognitive dysfunctions, like "finding the middle point and identifying the disregarded possibilities"
you'll learn to recognize the categories of each dysfunctional thought, like "mind reading, when you assume what other people think without having any proof that this is true". you'll learn to question these dysfunctional thoughts. you'll learn to take actions about these thoughts.
you'll learn how to prevent these cognitive dysfunctions. kinda like "change your mindset" but not in a coaching way lol that would be terrible. kinda like in a "let's reprogram this rotten parts of the brain", if you know what i mean.
i know that having a diagnosis/possibility like this is difficult. (i, myself got a bipolar diagnosis and was in total denial for 2 years) but it is freeing, in a way, because you can know exactly where the problem is. you know it's not your fault, it's a disorder. a mental disorder. it can be treated just like diabetes or a broken leg. you know exactly the sphere your problem resides. the exactly type of therapy and meds and what needs to be done.
maybe you'll find out that many of the things that happened in your life, some mistakes that were made, interpersonal relationships, social interactions, etc, were just a mental health issue that can be treated and get you in remission.
with all the love in the world, i wish you'll get a rightful diagnosis and can get access to proper treatment with good professionals and be surrounded by loving people that can be an emotional support during your journey.
this is coming from a 21yo girl, who is bipolar type 2, autistic, extremely anxious, that tried CTB once at 11yo, twice at 15yo, that survived to tell the story of her mental health treatment that gone well.
take care!
