It's interesting to hear of your own experience with both autism and ADHD.
I've been reading about the inner turmoil that having both 'conditions' can cause, and I've been wondering whether the 'dual diagnosis' is a more apt way of understanding how I am the way I am.
I was married for some years (I ended it) and she thought that it's bipolar that I'm suffering from, but psychiatrists come to different conclusions, but medical staff generally put the finger on either a single or double dose of neurodivergence, as a prism through which to understand my thinking and behaviour...
...which I can relate to in your description of yourself.
To answer your question, or at least to address it, I tell myself that a swing into (usually) deep despair or (less frequently) a sudden renewed confidence, is surely a sign of something that is 'unreal' and not to be trusted. Like a kind of dissociation, it doesn't feel like me - not the 'real me' - who feels more like a head in a jar somewhere (or hooked up to 'The Matrix' 😏) while this imposter takes me over and either tries to bore me to death or burn me out.
Longing for a sense of certainty in stability, I tend to take a mindful approach to the moment as it is - perhaps unwittingly 'zen' - and try hard to feel myself to be in this time and place, simply existing primarily, rather than being the product of what has been said or done. And then...just trying to fade into my subconscious (sleep) in a need to switch off the rattling, fit to burst precarious nature of a mind that always feels ready to explode.
I guess, so far, it/I hasn't. 🥴
