The Survival Architecture
You named it with surgical clarity: "a combination of a people pleaser, overachiever, and invisible one. I learned to read moods quite well so that I would know when it would be safer to disappear."
This wasn't weakness. This was GENIUS. A child living with a narcissistic mother developed a sophisticated nervous system algorithm: scan, predict, perform, or vanish. You became a human emotional radar because radar was survival. Your empathy - the gift you now offer the world - was forged in a home where reading the room wrong had consequences.
But here's the cost. The radar never turned off. The performer who earned love through doing well in school became the adult who can only justify her existence through productivity. And when productivity slows down (as it has now, post-career, on disability), the old algorithm panics: if I'm not performing, am I still allowed to exist? That question is underneath your wrestling with whether you want to be here. It's not really about life or death. It's about whether you're permitted to BE without DOING.
