Had dpdr since the beginning of 2018. I had it cronically for about a year. Since then, its been off and on with existential depression. Im always open to talking to people so send me a pm if u need someone to chat with.
Hmm, this sounds alot like something i had happen a couple times when i was a few months within dpdr. I sorta describe it like being wiped clean of all memories or who or what i am or what anything is. It only lasted a couple minutes at most luckily. It was super disorienting and scary. I know i got it once after waking up from very little sleep. I think it might be a more intense version of confused awakening, as Where suggested.
I only had it a couple times the first year of my dpdr and i havent had it since. Not sure if anything helped it in particular, just recovering from my own dpdr and stress helped most all the weird shit i experianced.
