Good luck with finding a resolution. I have often been told by people that I don't react to anything and that people can not tell what I am thinking or feeling (I am used to projecting a mask of either calm or stone silence, and in a lot of cases people have told me I'm intimidating, which makes me laugh given how I feel), and I tend to overanalyze things and intellectualize things sometimes, but I can't say I've got the same issue.
