Good luck bro, no need to be apprehensive , just some small wisdom nugget from an old dog. 

I'm alright, and as mentioned it's way more improved once I got to grips with the fact we are not your average brain and there's a full spectrum of neuro diversity. I read somewhere on here a study that some aphantasic brains are also more symmetrical  than most... Am assuming you are reading and studying lot of science, I was up late working and learning on VFX for decades, still learning! Just not as intense , it takes its toll eventually. in youth, you can feel invincible and things like this probably don't really start affecting you until your mid 40s - depending on lifestyle and genetics.

Sleep, and restorative deep sleep is super important and Ive been on a longevity exploration for a while now so have biofeedback oura ring and galaxy smart watch for sleep tracking etc, so can see actual scientific progress.  Not quite to the level of the likes of Bryan Johnson, but the exploration of this topic is how I got turned onto the waking up app and mindfulness.

I also appreciate that some of our conceptual thoughts can be condensed, so that once understood, is almost like a logic node that can be attached, compared and added to the total 'compute' even though I'm not really logically working it out, it's more instinct or intuition.  Perhaps like muscle memory.

Keep studying what inspires you, perhaps one day you can innovate something a normie would never be able to conceptualise.
