I've noticed this problem since around my mid-teens. Nothing I notice seems to be as vivid and lively like it was when I was a kid. I thought it was due to age, but now I'm not so sure. I looked up what this could be and I learned about dissociative and depersonalization disorders, and I can relate to a good handful of their symptoms. Nowadays, my reality looks dreamy and a bit blurred. About a week ago while I was driving, I slapped my face a little bit (not hard) to make myself feel connected to reality. I also sometimes look at items intently and try to force myself into thinking that it's clear, vivid, and actually in front of me. I only feel like this when I'm either anxious, or if I think about it. If I don't think about it, I'm relatively fine. I have had a history of high anxiety and fair amounts of depression. So I'm asking people who actually have these disorders if I might be living with this as well.

P.S. I've only recently learned about these disorders, and I'm sorry if I have offended anyone.
