usually when this happened to me my treatment providers and I looked at what was going on in my life right then. short version dissociation is a reaction to a trigger, there fore when my dissociation problems increased even though i was in therapy it meant I was triggered by something. my treatment provider would remind me to use my tools i have learned, (grounding, breathing, relaxing.....) and then deal with what ever was going on. that usually helped. if it didnt help it usually meant it wasnt a dissociative problem in me and we would take a look at my medications, and other issues that can cause dissociative like problems.

my suggestion contact your treatment provider, they will be able to help you figure out why suddenly you are having more dissociative like symptoms and help you to re ground yourself and feel better.
