I’m being bullied by a narcissist boss. What can I do?

I would encourage you to leave before you become totally destabalised. They do not change. They will be surrounded by their flying monkeys and harems so you will have little or no support.

My clients have been surprised at how many new work opportunities were available to them when they chose to leave.

Get suitable therapeutic support to process the trauma and establish if there are any links between this experience and your childhood experiences (I.e. control or bullying in the past would increase our tolerance in the present). Good luck with moving forward.
