Hi. Mum to ADHDer and small twins, so know to some extent about the troubles you face, although all situations are different.
I think you have to balance the whole "I don't have to explain myself to anyone" and constantly sticking to that, Vs "if I shared more, they would understand more."
It annoys me when you get threads full of "it's none of their business, judgemental arseholes" when it's actually, they call it how they see (however misguided) largely because the OP does nothing to facilitate a better understanding, all on the premise "I shouldn't have too." Technically, no you shouldn't. But it's this constant circle of they don't know how hard it is, but I don't educate them, on principle, so they continue not to know.
With eldest ADHD, I had similar, with comments of being lucky to receive so much DLA, what would I spend it all on. As though suddenly I had a free holiday fund. Of course that pissed me off. So I have two options. Do nothing to change the misconception that I had hundreds to blow on manicures courtesy of the government, or explain, how frequently I needed to replace carpet, furniture, clothing, cover the hours I spent with doctors, the school, therapists. The former, I keep my principle that I shouldn't have to explain. The latter, suddenly people become aware, more sympathetic, more educated, want to help, and critically don't have the sheltered thought process they had before when they meet someone else in a similar situation.
The second option, basically everyone wins. It astonishes me how so many people actively choose the former, because "principle" and "it's not my job to educate." Fine. But if you're going to abdicate any part of assisting a situation that you want to complain about, when it's in your hands to do something about it, then take some accountability for keeping the situation in the state it is.
