You wrote this awhile ago and I'm really sorry you never got any answers. That's hard. I think maybe hormones can play a role. I can be weepy out of nowhere sometimes because of that. and another reason could be a build up of emotion/feelings inside that all of a sudden reaches a release point and has to come out. Are things any better? Talking too much is one of those things that is a pain in school. ADHD doesn't help as controlling the impulse is harder. But this is not a moral or bad thing about you. :>) You like to talk. this could serve you well in the future, you know?
