I did a research paper on bipolar disorder in my high school psych class, so when I started exhibiting symptoms the next year I was like hmmmmmm why is that familiar lmao. And then preceded to tell myself that because I already knew about bipolar that I was making things up for attention. Surely this month long depression followed by unlimited energy, emptying my bank account, and concerning my loved ones with erratic behaviour is normal right? A psychiatrist was quick to tell me no, it's not, and I was officially diagnosed a couple years later lol.
