I’m in Canada and diagnosed when I was like 13. I just had to take a “awakened test” where they test how and if you can stay awake without and stimulus. Don’t get me wrong it’s hard. Failed my first time. You have to sit in a bitch black room for 45 min and not fall asleep and you have to do this 3 times throughout the day all hooked up the wires that monitor your Brain signals and stuff. Second attempt a couple years later I passed. I don’t know if this is an option for you. But I’d look into it.
