It clearly states in the article that a part of her illness was believing her family were conspiring with the police to harm her. So no, I don't think her family could have helped her.
The relentless persecution of disabled people by the state is enthusiastically supported by the electorate of this country. It's what people want.
It happened to me for years as I had the audacity to care 24 hours a day for someone totally paralysed. We were investigated endlessly. HMRC and Concentrix put us through a five month tax fraud investigation at one point. I was lucky to be mentally equipped to handle this persecution, but for someone who was also mentally ill, it would have been impossible. It is mental torture and it never ends.
