This sort of thing must severely piss off people with legitimate mental health problems.
As for if she actually has a mental health problem, it is possible; even high functioning autistic people can have their moments of darkness (as in, not thinking clearly). Now, considering how long the con went on for, it’s highly unlikely that she’ll be able to convince the doctors she was “insane” the whole time.
TL;DR: I’m not upset or worried.
