He feels like he can't be at home because 'they're coming for him' and he has to 'go into hiding'. He hasn't told me where he's going or for how long, but he's gone on foot.
I really just don't know what to do. I'm not necessarily worried for his safety so I don't want to waste police time.
He has been in contact with mental health services for a while but thinks they're in on it. As a brief background, he has been treated very badly by an employer (in healthcare) and has had some not great but not awful experiences with a GP and mental health services, and now believes there's some NHS/healthcare-wide cover up/conspiracy to get him. I don't know how to get him help when he thinks everyone is working against him, and if they suggest he goes on medication (which they have, multiple times) he takes this as confirmation that there's a cover-up and they're accusing him of being insane to deflect from what's really going on.
I'm just at the end of my tether with it all. I feel exhausted, defeated and just so, so sad.
