I've always known there was something wrong with me. I've always known the way I reacted to things and interacted with the world was not the best way. It became obvious with time and when I started to expand my social circles. During the last years, I've done a lot of self-work to get to know myself deep down and go to the root of things. I suspected I had BPD but a lot of people told me it was not possible, I was 'normal' but deep down I knew. I was diagnosed with ADHD and I FELT relieved and understood. A lot of things made sense! But then I was also diagnosed with BPD and my therapist told me my ADHD and my life circumstances made some of my BPD symptoms worse. Everything started to make sense. My best friend was the only person who always thought I had BPD and encouraged me to seek therapy and support because she does not stigmatize it.  
Once I got my diagnosis, I felt free. I felt like everything made sense. I suffered a lot during my childhood and teen years and once my therapist told me IT WAS NOT MY FAULT (the way I socialized, how I had no friends, my reckless behaviors...) it was all a consequence of the traumatic things I lived, I felt RELIEVED. I don't think having BPD makes me a bad person, I think it's a result of fuck\*d up stuff I had to live that's not on me. The way I have reacted to some circumstances is a result of my trauma and my condition. Ofc once you become an adult and you fully understand you have to take responsibility and that's what I'm doing. But for me, knowing the root of certain behaviors and feelings has been a game changer.   
Now, I have the power, I have the diagnosis, I understand myself &amp; my behavior and I'm working on them.
