First time in this section and hoping for some advice. My mum suffers (I think) from paranoia or delusions or something. She has a very very elaborate conspiracy theory and thinks that everyone in the world is linked in some way in trying to cause her trouble and laugh at her. Basically about 20 years ago she was made redundant, and admittedly it was probably due to her face not fitting. This caused her a lot of stress at the time and she did take action for unfair dismissal and won. But on the back of this she thinks that everyone is out to destroy her. That she upset the wrong people and now everyone knows who she is, she says there is stuff about her online (I can't find it and neither can my dad, husband etc), she said that there are code words and people can score points for finding out info about her etc etc. she has mentioned this is the past and we've tried to calm her down and brush it off as it seemed to sort of go away. But now it's come back and she thinks my daughter should leave her school as one of the teachers looked at my mum oddly so it obviously part of this network. She thinks my neighbours are too. And she thinks it stretches worldwide and on holiday people are taking photos off her to score points on this secret website. It's really scary and today I just asked her to leave as I couldn't cope with the outpouring. It's all so weird and what's most upsetting now is that she is bring my children into it. She thinks that my sisters boyfriend broke up with her as he was paid to by this mafia that she thinks is around.
Is this paranoia, or delusion? And what can we do? I totally appreciate that the redundancy thing knocked her and I am not naive, I know that some people don't like certain people and want to make their lives hard. But there is no tangible evidence of anything.
I am sorry , I know I sound harsh but I am so frustrated.
