Your understanding is pretty much correct.
An unmentioned danger here (in addition to self-fixing) is e.g. the autism industrial complex trying to convince the parents their child needs to be "fixed" early on through their absurdly expensive, completely ineffective and pseudoscientific, horribly mentally damaging "therapies."
Certain kinds of "self-help" books targeted at neurodivergent people are the equivalent of that for teens/young adults who think they need to "fix" themselves.
Of course, first and foremost, one must understand and accept the risks.
I do suffer from ADHD (which has been getting more severe over the years), which leads to anxiety and depression (I call it the ADHD->anxiety->depression circle, vicious thing).
It doesn't have to be accepted. It needs to be fucking fixed.
I am in Europe, where it's "accepted" as laziness. So I can't get proper medication and recently started my own mini lab risking years in prison. I realized I am absolutely, undoubtedly fucked without medication, and that's the only solution I came up with, judge me lol. Chemistry is fun, though.
I think you need to be careful with this advice, as I can imagine people reading this and trying to fix things that they can't, and then getting frustrated and/or depressed when they can't.
I imagine there are lots of younger people with ADHD/Autism who would feel that their neurological condition prevents them from fitting in, and so would feel that their brain needs to be fixed, when really what needs to change is acceptance of these sorts of conditions. That's my understanding of the whole "embracing neurodiversity" movement.
