ve been to the ER five times, had a whole bunch of tests done, and I think the general
crazy feeling is usually just from copious amounts
of anxiety, stress and
fear... I know I've been under the most stress I've ever had and I began to experience something called derealization/depersonalization, which is an EXTREMELY scary feeling, you feel like you're not real and you freak out, but I really think that enough stress and anxiety can make us feel like we're going crazy.
