MOOP!

I have the same problem.

I've learned that externally vocalizing these "train-of-thought" ideas is supposed to stop somewhere areound the age of 6 or so, and then these thoughts are supposed to become an "internal monologue".

I apparently never got that memo. I still "talk to myself" in a lot of situations. It has cost me jobs. It has caused people to think I was mentally ill, costing me relationships. Learning to "shut up" and think these things rather than say them is frustrating and it's extremely difficult for me to not be able to vent immediately. LJ helps. Keeping a place to put my thoughts always has.

I have gotten a LOT better, but it's a comfort issue with me. I get upset/frustrated/scared/angry/stressed, I start "talking" again. It takes a LOT more impulse control than I normally have to NOT say what's on my mind.

I wish it weren't that way, but that's what people expect.
