I know CS doesn't want to talk to me but, just adding my own irrelevant side thought while reading this thread.
Completely going out on a limb here, a lot of people throw suggestions what causes you to be the way you are, but, I wonder if there was a high degree of emotional and physical neglect in very early childhood that caused, perhaps an attachment disorder of some kind of just, stunting in certain areas.
Like, if during the crucial developmental windows, there isn't proper nurturing and bonding with, a human, ideally the mother, then... it causes, developmental delays. Neglect and maltreatment can cause a whole slew of life long deficits.
It's really fascinating when you research more into all about it. Developmental psychology and the affects of neglect, abuse, isolation, etc.
And also, attachment disorders.
Could also be, later affect of neglect, abuse, trauma, or other unhealthy dysfunctional aspects in your life at any point that maybe affected you more than you know or realize. Not just early childhood. Trauma (bullying, SA, CSA, etc) and dysfunctional families (so many different examples of what constitutes a dysfunctional family dynamic) can really, have quite the impact.
It's okay if none of this lines up for you, but, just one perspective of many plausible explanations. Regardless, still interesting to read about.
