Something I've come to realise is that I cannot expect anybody else to have an in depth understanding of ADHD. I don't, and I appreciate that, for example, I myself don't have a very in depth understanding of dyslexia, or T1 diabetes, or hypermobility, or food allergies, or chronic fatigue, to take a random selection of issues that people I know and love live with. I have an in depth understanding of ADHD because it's
my issue and my son's issue and so it's important to me to understand it. I can't possibly understand every single issue somebody might have to the same extent. And so I respect that other people won't know everything about my issue either.
So I no longer feel annoyed about people not understanding subtypes, and nor would I expect other people to automatically understand if I say "Oh I have ADHD, please support me". Instead I ask for specific things "Please can you send me this information in an e-mail?" "Excuse me while I write this in my calendar before I forget" "Could I give you money towards the picnic rather than bringing something? Let me give it to you now".
But I have never said things like "Allergies aren't that serious, I'm sure he'll be fine if he has a little bit of milk powder". I listen to the mum of the allergy kid because I know she has much more of an understanding than me!
I do not say "Well I tried so hard to help that dyslexic person but he just isn't trying hard enough." or "Why don't you just use spell check?" I don't know why spellcheck doesn't work for dyslexic people but I know that would be incredibly annoying.
I don't decide randomly that it's best if the person with diabetes eats this food rather than that, because I have no idea what is the best way to control blood sugar levels with diabetes, even if I did read an article about it in a health food magazine.
So if you do not have an in depth understanding of ADHD, that's absolutely fine, but please don't go around pretending that you do know about it (by saying that it's overdiagnosed, or overmedicated, or that XYZ therapy is better than medication, or that medicating children is "sad"). It's okay not to know about something. If you like, you could ask "How can I support you with that?" But mainly, just understand that it's OK not to know a lot about a subject and just be alright with that.
