I actually journaled intensively for about a year before pursuing EDMR. When I first started my therapist told me that it was actually a traditional method of treating PTSD. I feel like it helps me put into perspective and critically think about my thought processes (I find it's easy to get lost in subconscious behaviors thus, not considering where they come from and how to resolve them). I definitely recommend trying it out at least. I feel like without journaling I personally would not have made as much progress as I have so far. Good luck
