I initially didn't recognize my hypomania as anything more than being better after being depressed. I didn't realize I was a condescending arrogant jackass. I really believed I was substantially smarter than anyone around me. When I started having delusions of immortality it was a little more obvious to me but that wasn't happening yet at the time I was originally diagnosed. Anyway, it is possible that you have had more episodes that you didn't recognize as such.
