I've pretty much exclusively had derealization. I can't recall having depersonalizaion to a level which really bothered me. I did have a fairly significant breakdown of the 'self', but that was much more to do with having an existential crisis. For me, the feelings of unreality, brain fog and existential rumination (all derealization in my case) were far stronger than anything related to depersonalisation. I almost always felt like myself, but it was the world outside that felt completely and utterly bizarre. I've also never felt detached from my body or anything like that.
There's never going to be a clear reason why you have DR but not DP - we're all different. I'd suggest staying away from marijuana while you're experiencing these feelings. Feel free to ask any questions if you're feeling scared.
