I find EMDR really tough. All the parts of me connect up and I lose the ability to make them shut up, I have to listen to them instead.
EMDR makes it impossible to avoid the stuff that you've been hiding from yourself, or running away from. It turns out that I (and you) had a good reason to avoid that stuff, which is that it's really difficult to confront it!
But not impossible anymore. We're both older and wiser than we were, and we have more coping methods. We have therapists, and social supports that we didn't used to have.
Hang in there. Once you're confident in being able to endure what you're facing now, everything else gets easier.
