I don't even think it means I'm particularly "smart," whatever that means. I just picked up one specific set of skills extremely early that happen to be highly valued in young children.
It may also be related to trauma. All of those I know with earlier memories were almost always in an unsafe home environment, eg: narcisstic/abusive parents. Probably kicks your memory into high gear because suddenly it matters that you remember what to do and what not to do to avoid injury or pain.
Hmm. I could definitely see that. Learn to speak early because the parent obviously isn't recognizing and responding to your needs the way you're already trying to communicate them (not that it'll help; not being able to understand isn't the narcissist's problem). Do your best to create extensive mental pattern lists of safe/unsafe things to do or say (not that it'll help; narcissists aren't consistent even with themselves). Do everything in your power to seem like those bigger people who are safer than you (not that it'll help).
It's amazing how much growing up with a parent like that can mess you up. I actually thought I had undiagnosed high-functioning autism for awhile, because I thought I was terrible at reading social cues, and was so easily and frequently overstimulated. It took some serious therapy to discover, no, I'm fine at reading nonverbal and social cues. I just spent the entirety of my formative years being gaslit at every turn about what my dad's expressions meant, so learned I couldn't trust myself. And I'm much more highly attuned to my surroundings because I spent the entirety of my formative years knowing threats loomed around every corner, because ANY wrong thing could set dad off. It was trauma, nit autism. My parasympathetic nervous system never learned to come online and down-regulate, because the threat was never over. My body and brain developed in the constant presence of cortisol and adrenaline. That does make it so I'm easily overstimulated.
One of the things I'm working on is cultivating gratitude even for the worst things in my life, in light of the goodness in it now. I wouldn't be the same me were it not for those things, and if I'm grateful for who I am now, I can't really pick and choose which parts of that history I'm grateful for. I don't really like that it's all-or-nothing, that I can't be completely grateful for the present if I still reject my past, but it's working a lot better than anything else has. I do not and will never condone many of the things in my past, but being grateful for all the parts has been part of my journey to gratitude for the whole.
This gels so much with my experience, thank you for sharing. The lack of down-regulation is exhausting at times.
Your work on gratitude mirrors my experience as besides that and some psychedelic experiences to help process from a less traumatic dissociative state were some of the big keys for me helping to process the grief and anxiety coming from those experiences. I wish you the best! Breaking a trauma cycle is beyond difficult and tiring.
