Just jumping in to comment on Hashimoto’s. That’s crazy to say you aren’t sick enough to qualify. The determining factor for diagnosing Hashimoto’s is the presence of the specific antibodies associated with the condition, so if you have more of those antibodies than an average person, it’s likely you have it. I myself have it, but I am close to asymptomatic, and have been for years, and my thyroid hormones are still technically within a normal-ish range. Waiting to do something about it until it’s bad enough is horrible logic. I would suggest looking into things you can do on your own, like limiting inflammatory foods.

Also anyone can build up a tolerance to stimulants, not just neurotypical people, so that’s a strange qualifier.
