@milkysmum I am similar.
I have 1 memory of my childhood - it is a vague flash of a door opening on to me and the lock part cutting my forehead open.
I have no other childhood memories, not of school, siblings, holidays, grandparents, anything.
I have 1 memory of a moment of the final day at my highschool before I moved 1700+ miles away, where I knew no one and had never been.
I don’t remember my wedding, my DC’s birth, their milestones, nothing. I have to work out my age every time I need to know it.
I can sometimes recognise the events that old photos show, but I have no associated memories of the actual events depicted.
I have no visual memories, no mind’s eye, no pictures in my mind, I have never remembered a dream.
I didn’t realise for the longest time that this was different to most other people. It is very isolating, lonely and impacts greatly on my life.
