As Bec said, and really Faerie also confirmed, it is great for one or two isolated events, but if you have significant trauma that is "extended" over a period of time, then I would recommend that you do not go near EMDR. If you have one or two incidents that are abnormally traumatic, then it may do something for you, depending on the severity of the incidents, but the facts are, that if you have hidden trauma, EMDR can bring back too much at once, thus overload your brain and cause brain damage of varying severity. EMDR is very good for one or two isolated incidents, but any specialist that is worth their weight in gold with EMDR, would not even attempt to do it on someone with long standing military conflict, childhood abuse or a person who has been raped multiple times throughout their life, because the chance of brain damage is far to high, thus it is normally recommended to those people to move toward CBT instead, where the mind controls how much is released at once.
