I (21F) was diagnosed with Borderline Personality Disorder at the age of 16-17. Now, I have seen a-lot of therapist since I was 5 and most of them just tell my mom that “She’s just depressed” or “She might have Bipolar”, but whenever I got a new therapist, she asked me if I had ever heard of BPD. Now that I am a bit older and have a somewhat understanding of BPD, I truly don’t understand of What caused me to have this disorder? Or How did my other therapist and psychiatrist not know about this?
