Ah, now I understand what you meant. The OP assumed the "get diagnosed" part would be understood. I've made it explicit below:
> Here’s an example: you (having undiagnosed ADHD) try to set a schedule, or use a todo list, or clean your bed every day, but it doesn’t stick. So you [get diagnosed and then] get on medication, and the medication lets you form your first habit: which is using a todo list app consistently, checking it every morning.
At a certain point, if someone doesn't understand what you're communicating, it's a problem with your communication and not with them. Personally I still don't understand what you're trying to say; it wouldn't hurt for you to expand on your point if you want someone to respond in a useful way.
> Even assuming a health care system that actually cares about ADHD in adults, "just get a diagnosis" seems like a much higher bar than "just clean your bed every day".
I would elaborate if I understood how there's any room for confusion. I don't.
Getting diagnosed is the first step. It can be a steeper step for some than others. But once you have a medication that works for you (which sometimes takes a few attempts) then you'll find that task avoidance becomes less frequent. Having a to-do list will help you ensure that the "must-do" tasks get completed. I rely on my phone's calendar, task list, and a journaling app named Daylio that I use to track how effective I was in completing tasks that day (you pick an emoji)
I was fortunate to find a physician that specializes in ADHD. Most of his patients are children/teens but they also see adults like myself. You can also go the route of seeing a psychologist that specializes in ADHD.
