In my inaugural post on this forum, I mentioned that I feel that I have deadened my emotions since I was young because I feared that empathy between myself and other people left me vulnerable to emotional manipulation (such as sulking or anger). As a consequence, I know have a lot of control over my emotional state and am extremely good at suppressing my feelings in situations where it is beneficial. This is not to say that it's comfortable to do so--on the contrary, it's usually at least somewhat stressful--but that it's a finely-honed skill I've developed as a defense mechanism. I think my primary reasons for doing this were because I moved a lot as a kid and was always an outsider, and thus vulnerable to ridicule, and because my sister and father were emotionally manipulative (I think they're INTJs, maybe a bit sociopathic).
Has anyone else done this? Or am I just nuts?
