Sorry for posting so many times. My depersonalization and anxiety is gone, now I have this extreme irritable nerve sensation for absolutely no reason, its not that I am just annoyed, it is effecting me physically, it makes my back sore and spine stiff like I have been exercising all day. The day before I felt energized and good, because I was excited about painting and had something new and exciting to look forward too. Could this be some type of mania?
