I have constant derealization, yet I am not anxious alot. Can this DR be from anxiety, even though I still feel it when I am not anxious at all?

Have a psych eval. It's hard to decide for yourself what your mental and emotional symptoms require. See an expert for a Dx and try to be descriptive rather than using the professional sounding words. Talk about what happens when you feel these things and bet very detailed about when, how long, what happens in every way. Best!
