I’m having the same thing but I still feel like it’s something more then derealization and I’m genuinely scared, I feel weightless and hollow and I keep questioning if I exist or not because this doesn’t make sense! Sometimes I’m more calm but the feelings don’t go away, very single day it just gets worse and worse and I don’t know where I’m actually going it feels like I’m going down a bottomless pit and nobody else can relate. I keep feeling more and more disconnected with reality by the day! And in a way my mind feels like infinity! Can a brain actually do something like this?
