" unparalleled creativity, launching me into a realm of ideas and energy that defies description." I can relate such episodes, and I still experience them, but I've learned to reign myself in. You're fortunate that you haven't had to deal too much with the other end of the spectrum Aidan, because it can be so damn unnerving - to go from zero to sixty in a matter of days, hours, or even minutes. Sometimes, just the wrong word or expression can completely turn around, what was just viewed as a perfect day. The good part is, it helps to learn and get to know yourself, so you can provide the right kind of self talk. Thanks for sharing your never-ending journey :-)
