I cannot do EDMR or any of the usual processes tried. Too much trauma.
I know of many people doing EFT and similar processes (the Healing Codes, with Alex Loyd, as well). Many are doing well with both of these processes.
However, I have only, so far, seen the EFT (and yoga) endorsed by trauma researchers/specialists, esp Bessel van der Kolk.
I go into severe PTSD with EFT, too.
I have seen a few researchers and they tell me to not do any of them due to the chronicity/severity of my trauma history. That is an individual recommendation, not necessarily to be taken generally here.
I hope EFT helps you, too!
