I just said for me.. the therapy did not work... in fact turned out to be very bad for me... and yes I went to a very experienced person.. My Dx is DID... and for me it brought me to those traumas.. and "left" me there...
There were residual effects after treatment that were intolerable.. and I also was in talk therapy... I think that it can work... but perhaps it is not for everyone... it is powerful.. and it should be approcahed in my opinion.. with caution.. just like any treatment plan..
