The debilitating nature of episodical is dismissed, in addition of dismiss the aftermath suffering and prolonged recovery. Each of such recovery requires the suffer's steely strength for not giving up.
Some government agency told people reporting weeks of hospitalization due to mental crisis. The response was 'okay, your disability lasted 2 weeks. The requirement is 90% of time'. And worse, other agency would use this as a proof that the episodical disabled is not DISABLED.
