I don't know what you are like normally vs. depressed vs. manic, but your threads seem a bit dis-inhibited in the sense that regardless of if there is a reply or not, you elaborate on your original idea. You also seem to jump from one idea to another fairly quickly, not sure if that's characteristic of you.

It's hard for me to tell for myself too, because i am usually quiet/have no reason to speak/ chilling/ content, even when hypomanic sometimes, but once i get into a conversation it seems like words just come out as if i had been thinking about what to say for weeks, as in, everything is very fast, strong and intense, even though i am thinking on the fly
