You need to discuss this with a pdoc or therapist. However I do know I have had memory blocks related to my abuse. For me it wasn't so much that I couldn't remember is that Actively avoided doing so. When my PTSD got really bad, I couldn't stop remembering and having flashbacks. That situation has greatly improved with therapy and meds.
I have a large span of time where I have major memory loss (like a decade) due to a prescription med that damages the memory retrieval process. It's insanely frustrating to try and remember a time and find nothing but a blank. Ex. I know I had a 21st birthday. But I can not recall anything relating to that. I don't know what I did or how it felt. Nada. A huge gaping black hole.
So I do understand how frustrating memory loss can be. Try and relax. The more you struggle and tense up, the more frustrated and anxious you will be. Be kind to yourself. Think about getting a pdoc or skilled therapist's opinion to how to proceed.
