>> she’s become seriously unhinged.
Not sure the reason, but ditto the unhinged part.
Ann has always said things that others won't and she has always gotten a rise out of people for saying those things. As the years have passed, people have gotten used to Ann and just blow off some of the things she says as being "Ann", so she has to say things a little more outrageously. It gets worse so that she can still get a rise out of folks ... unfortunately it doesn't always reflect well on her and it is a vicious cycle.
