Questions about CPT and EMDR

Hi there, I have had anxiety for nearly a decade, undiagnosed until last year and have been working with a therapist online for the past couple of months where we finally cracked that I have PTSD from unprocessed CSA. I've been working on elements of CPT with my therapist including stuck point and big picture worksheets, but I wonder if I am hitting a plateau and unable to continue working forward.

Does anyone have any less-clinical insight to CPT and/or EMDR, experience with, know a bit more about it than what google relays to searchers?

Thanks,

Jo
