Yes, and it's likely due to low-intensity disorder showing up as something one can control, manage, compensate for, and find a place for oneself in society, but if somehow the dial gets fiddled with, things start to fall apart as we move up the sigmoid curve, positive feedback loops turn negative, and a state sponsored suite soon seems sensible.

In other words people with mental illnesses/conditions/disorders/syndromes doubt their own diagnosis, because sometimes it "just feels like an adorably tiresome behavioral `oh you` that everyone laughs at", and other times the wolves are howling inside and suddenly you understand every and all kinds of disability, escapism, compulsion, and serial killers, as you are trying to cancel plans, make up excuses, ask for help, while - by definition - fail to do any and all of those as a headwind of hurt hurls heavy and hopeless.
