“he has suffered another serious episode” says his wife, which suggests he has tried to take his own life. That will be why he’s been admitted.
Inpatient mental health hospital is NOT the same as the priory rehab facility which celebs self check into… ie Katie Price.
An inpatient mental health hospital is only available to those who are seriously mentally unwell/ in crisis that cannot be managed at home. Even if you can pay.
He will likely be on constant or 4 hourly observations, ligature points are minimal- they will have special mirrors, curtain rails and clocks. Nothing off the shelf can be installed- it’s all specialist items to minimise risk of self harm. You don’t want to be there unless your life is at risk.
Get your facts right before you spout crap about using mental health as an excuse!
