Yes,definiteley. My dp/dr changes all the time.. every month is different like really my dp/dr is progressively getting wors and worse. I’ve always dp/dr I guess my whole life but it was livable I felt myself.Now I am totally lost into the void if manifested itself into a very sick disorder. The DR is soooo bad no depth AT ALL. My head feels the same as you it’s so hard to describe,I also feel like I have character switches,like DID but I still notice them switches and I get spooked out about it like why am I behaving so different. i am messed up,but you’re not alone in this I have the same thing..I am not on any medication as well
