I am sorry you were bullied. It’s terrible. It’s possible you have triggers steaming from your past. Could you address it with a therapist? I’d try not to self diagnose or diagnose others because it’s usually serves no purpose. PTSD and narcissism seem to be new trends nowadays, it comes and goes like this. All of a sudden everyone has one or the other but no formal diagnosis. I recommend to avoid it as not every trigger is PTSD

I strongly recommend therapy
