Why do I cry at the drop of a hat?

[Flo Mingo]

I have lived this reality for a long time and I'm trying to understand why. I'm emotionally intelligent and work through my issues via self analysis and a belief that the Universe is perfect. But here's my "problem"; when I speak, if I'm at all emotionally or empathically engaged what I'm saying, I cry. The catch comes in my throat, I swallow hard, pause, think of something unpleasant or unappealing, etc. But nothing stops the tears from wanting to flow. I mean, like ugly crying over a story or thought or inspiration or whatEVER.
Help me out. Is it just me and how do I keep my empathy without having to bawl like a child over it?
TIA
