i was talking to a few nurses during covid that lost their jobs eventually for refusing the jab. they all said they noticed huge personality changes in colleagues that took it. not just shunning them for being unvaxed, but also ones that were caring and had great bedside manner become rude and short tempered, yelling and abusing patients even. so I wouldn't be surprised if there's been an uptick in mental illness

Yes, mental illness is very common in nursing, but it develops as a reaction to the hopelessness of being subordinate to egotistical narcissistic doctors. When you're dying in a hospital, the nurses can save you, but half the fight is with the ignorance of the doctors. I know this from experience as a patient. And nurses will tell you : the best way to survive anything is to never stay in a hospital.
