It’s true that bullying is learnt behaviour which passes from antagonist to victim, who can then become an atagonist themselves. Of course, not all victims become bullies, but many do. Many become supportive empaths, people such you and myself. In my case I was bullied interminably by some horrble boy who set me up for a beating by fifteen older boys, which almost cost me my life. Like you, I was traumatised for most of my adult life after that. Indeed, even right up to now I have my moments. Fortunately I can bring the symptons under control. Anyway, be good, love peace and joy to you on your journey.
