Stop armchair diagnosing and leave people alone

Saw this tiktok and initially thought it was just another possible faker yet opened the comments and it was full of people armchair diagnosing. The original commenter explicitly said “I’m NOT a system” which if someone says you don’t question (unless you’re their psychiatrist/psychologist who has enough evidence to doubt). Yet, the replies are almost ALL people armchair diagnosing someone on the internet from a singular comment of them clearly stating they aren’t a system. I know the first person was apparently joking but it doesn’t excuse the behaviour whatsoever.
