To preface this I'm not diagnosed and not seeking a diagnosis, but was hoping yall could shed some light. All my life has felt like a sound wave of ups and downs, if that makes any sense. And for the past couple days I was on one of those highs, where I felt especially social and extroverted (which is not me most of the time) where I had this above- average opinion of myself. I felt like I could do anything and quite literally wrote my own language just to see if I could. I also bought this big ass hat for way more money than I should've just because I was hanging out with friends and thought it was funny. Now I feel like my normal self, not quite in a pit of depression but generally unhopeful about the future. The things i was interested in seem pointless, boring, or stupid. I know for sure I go through bouts of depression and I've found ways of coping, but every once in a while this erratic behavior surprises me. Is this similar to mania?
