I found out recently that especially towards the end of my session, I tend to get stressed and anxious, causing me to dissociate. I told my T this, so she's aware of it. I still joked that I need to bring my own notebook to make notes (In hindsight, it seems like a feasible idea).
So yes, I battle too. Luckily my T takes notes, and if I forget what we discussed by the time I get to my next session, she can fill in the gaps for me.

I generally find that I am battling with my memory a lot recently. Not sure if it's my psych meds, or stress/depression
