Really short people with some fat/muscle always look a bit chonky (she's 4'11)
It takes a while to get rid of body fat, and if she is just focusing on building muscle and not getting lean, it'll probably be hard to notice for a few months at least

I wouldn't put it past Anita that she might have at least one of these disorders. Narcissistic Personality Disorder in particular
To be fair, the knife one seems arguably pretty reasonable given the state of the police in the UK. I'd rather not get personal on here of course but I have firsthand experience of an at least slightly similar situation and the police weren't interested.
If a woman calls the police and says theres a man in my garden with a knife.. they show up and remove him, might not take it any further but they dont just ignore it, especially if hes "camped out"
