Like you, I'm in my 50's, and after I kind of had a melt down and told my T way more than I had planned, he immediately suggested EMDR. I was worried about reliving years of memories as well. Once I learned some grounding techniques things have been pretty good. I really need them to get through the day sometimes. I've found the flashbacks/memories come whether I want them or not, so I'm trying to learn what to do with them. EMDR seems to be helping that. I'm still early in the process, only 2 sessions so far, but I'm managing better between sessions.

Like Breadfish and Pattijane said above, you are in control and don't have to dig into details or share anything if you don't want to. It really is in your hands. I have been in other types of therapy and I'm finding EMDR more manageable than those in the past.
