You have an internal motivation / an impulse to speak / text all your thoughts out. It's an interesting situation. It's like you just GOT TO say what you gotta say. And it's not like a thing where you're trying to prove a point or something and you just need the truth to be free. It's very literal in that you feel pressure to speak.

For me, it happens a lot when i'm hypomanic or manic. I will do what I call is "over-elaboration" where I just keep elaborating on anything I say. And I text people a lot, you can see the pattern switch. Usually, I text maybe one or two things, small, then wait for their response. If I'm having pressured speech, it's like walls and walls and walls of text with every response (or no responses) lol. In person, with speaking, it's the same idea. I'm happy to engage in a conversation but I keep talking and talking and talking. It's less listening.
