Downvoters, I am curious what the objection is. If I may elaborate on the second paragraph, the situation I am describing is one where someone is harming themselves or others, but saying everything is fine and refusing treatment. Then they get treatment, they improve for a while, and maybe you see some behavior that reminds you of that earlier episode, but they insist they're fine again. So you might ask: is this a relapse into delusion? Or are they really fine? Honestly it is tough to answer. When you have seen their condition hurting people and being kind of dangerous, it's easy to get scared of misjudging that situation.
