In some ways we do choose who we are. You've done that. You're a more positive person, responsibility and integrity mean something to you, despite the bad examples in your childhood.
Love this. It's so true. I sense that Sunny Sunglasses has figured that out, despite growing up in a challenging environment. Sunny feels responsible for her life, she has agency, she can choose her next steps. She can tolerate some discomfort for a time, and persevere through challenges and setbacks, because she sees a path forward to something better. Basically she chooses to be positive, and that is probably one of the most powerful forces in life. Happiness is a choice.
I find that the disposition of someone with BPD is basically the opposite. The default thinking for a pwBPD skews very negative. Granted, thinking about what could go wrong can be protective sometimes (to avoid harm), but too often with BPD, their negativity is extreme, pervasive and reactive. Worst of all, a pwBPD doesn't feel responsible for her life; instead, she thinks that other people are causing her life to feel miserable. This mindset is pernicious, because it's basically a form of learned helplessness. She has no agency, no power to move forward, let alone see any good in people (including herself), or give the benefit of the doubt. She's stuck in a negative thinking rut. Worse, she lashes out and blames others, trying to make them feel as miserable as she feels. It's truly depressing.
