Hello! Saw your post and thought I’d reply because I also did not smoke weed or have anything traumatic happen to me. I believe my dpdr was caused by anxiety (I went through several months of extreme health anxiety and OCD). I don’t think it necessarily has to be caused by a huge trauma, prolonged stress and anxiety can do it. But I would definitely encourage you to see someone, whether it be a gp or therapist if you are able. My doctor was very understanding of these feelings, and my therapist helped me work through them. I feel like all of us feel like these symptoms are so odd that they’re difficult to talk about or explain to doctors or therapists, but everyone I’ve talked to has been knowledgeable about depersonalization and very understanding too. Best of luck to you if you do decide to seek help!
