In my 40s and diagnosed with ADHD with addendum '... Suggestive of also mild Asperger's'.

Initial reactions from close people in my life was 'this explains so much'.

However, I still have to repeat 'you know me right?' when I experience frustration from people in respect to my reactions and behaviours to certain situations.

In hacking the system, I've built many masks and skills to function in the framework of conventional society, My underlying function though still creates reaction / actions that others can't understand and the conflict in my appearance of functioning normally at the surface to my true nature when it appears confuses people - 'does not compute' with their underlying picture and framework that they use to label people.

Mostly people want simplicity and place people into boxes and order life into clear categories. Asperger's, ADHD, OCD, etc etc creates multi dimensional interlocking dynamic spherical Venn diagrams of personality, and people can't easily label and so do not want to spend the time trying to understand.

Look around and mostly 'typical' people won't spend time trying to understand themselves and how and why they think and act in certain ways, those that have always been 'a little different' look inwardly far more, so I'm not surprised that the world is full of misconceptions and quick judgement. I chose to ignore it, embrace myself, and just carry on life not caring what people think about me.

For those that are younger and struggling with not quite fitting in, or struggling to be accepted into 'normal society frameworks', don't lose your true self, embrace and understand who you are, own it, admit it, and those that accept you for you will stick around. I wasted far too much of my life trying to be accepted and appear normal, it's tiring and not truthful.
