Yes, I can totally relate to what you describe. Since discovering AS (diagnosis in progress but feel pretty certain), one of the aspects I have been having the most difficulty with is my (possibly willfull) ignorance of things I feel I should have been a lot more aware of. When alone, I tend to exhibit some quite autistic behaviours that I was aware of enough to semi-conciously make sure I didnt do in public. Still, every time I would get to thoughts of why I did them, I would brush the thoughts aside and tell myself that I am just worrying over nothing and imagining problems or that everyone else probably thinks the same etc. I have done this for years.
Also, I would always think of myself as being very in control of my emotions - even pride myself on it. After some self-analysis and reading up on AS and alexithymia I now realise that I actually have serious problems even recognising my emotions - both that they are present and specifically what any given emotion is. A lot of the time my answer to how I feel if asked is pretty much based on what I expect the answer should be given the context. Since it is second nature and always has been I never really thought about it until now - quite a thing to get your head around at 30.
I digress but the point I wanted to make was that you are by no means alone and, speaking as someone who is realising new (sometimes slightly worrying or disturbing) things about himself every other day since discovering AS, I think I might have some idea what you are going through and how strange it can be.
