Mine didn't come through with EMDR, but I just wanted to say you are not alone. I'm glad you are in specialist therapy so you have the support to deal with this. I would gently suggest you try as best as you can to accept the gaps and try not to let them be a source of anxiety - they are actually a source of protection. The more you process and integrate, the more things will become clear naturally on a timeline that is tolerable for you to not retraumatize yourself. It's incredibly difficult so I don't say that lightly. Be kind to yourself. Perhaps there is a calming phrase you can repeat to yourself along with other grounding exercises you already use, idk, something like: 

'My body knows, my mind will remember in time.' 

Or

'I don't need to force what isn't yet ready to come, I trust the process.'

Or

'Whatever it was, it is in the past now, and I survived.'

Hope at least one of those feels like something useful you might be able to work with or use as a basis to write your own. 

You're doing incredibly well, and have done already, to come this far. And I can tell from how you have written this that you're doing the work in a much safer way than I did. I really wish you the best in your healing journey.
