So... I found out I have a BPD diagnosis on paper. A year and a half after it was given to me. 
Backstory: I was hospitalized for a suicide attempt, which is when the diagnosis was given. That time of my life is pretty foggy in my memory, but I do remember a doctor reading me my medical record - but without including my BPD diagnosis. He only told me I have depression &amp; substance abuse. No mention of BPD. 
I was seeing a doctor last week, and she pulled up my medical records. It's been a year and a half and this is the first time I ever heard I have been diagnosed with BPD. I had multiple partners and other people in my life asking if I have it or joke about it, and I have read through the symptoms being like "huh this sounds like me." But like... actually finding out there's a legal file with my name next to the words Borderline Personality Disorder was a shocker.
