For people here still struggling with their bullying (past), I’d highly recommend Cognitive Behavior Therapy together with EMDR. The same professional applied both techniques in my case. It has worked wonders for me and the painful past is much less painful now. Having being bullied no longer define my sentiments and outlook in life.
Asking because it's something I've looked at for unrelated reasons, and while the couple of providers I've interviewed thus far I disqualified for other reasons, if there's more to look out for here it'd be good to know about.
