yes, i know that. mine has been changing every couple of days for a while. sometimes I was also agitated, aggressive and overexcited. I had phases when I didn't really feel bad but just wasn't interested in anything, I was basically "cool". mostly combined with being annoyed a lot by things or people. for example if some person talked to me and I was annoyed I didn't bother to listen or answer but just left. it felt automatic, like I was a robot and I was obliged to leave because the annoying talk caused it. I knew I was impolite and didn't want that but I think this is something my body did, not my personality.
funny feeling.
