Wouldn’t surprise me.
I had a massive psychotic break 5 years ago. I’m pretty sure it came with physical brain damage. My memory isn’t what it used to be. There are holes in it. Apparently some of it is so completely gone, I don’t know I’ve forgotten it. Usually I know if I forgot something because there is a dangling pointer to it.
Brain damage feels distinctly different. The problems from being bipolar has very sharp lines in my brain. It’s known territory. Damage is foggy, indistinct.
Things have definitely healed and I’m getting function and a few memories back. The foggy areas have mostly cleared up. It’s been an odd experience.
