Happens to me quite a lot. Not sure if that is related to type. I've also cried because I was angry that I couldn't stop the process of crying no matter what. When it happens, it seems better to just ride it out or find a distraction.
That said, this post triggered some memories of me as a child sobbing in my room, upset and confused why I was crying and why I couldn't stop crying.
I also remember as a child thinking I had two separate facets of my self: A Logical thought stream that would talk endlessly in a monologue (asking rather profound questions about myself, the experience of being alive, ex. why can I see other people's eyes but have to look into a mirror to see mine? and the world around me) and the less tame, wild animal that was the emotions.
