I have a problem differentiating the two.
I have to have things in the right place, so that I can find them - keys, TV and other remotes, phone, cat's medication, and if anyone comes to the house I insist that they put things back where they found them. If I can't find important things like this I go into a tailspin.
When I go to meetings, I take very, very detailed notes for myself, as I can't always remember or retain information. This works for me as I can refer back (I prefer good old-fashioned notebooks for this purpose, and paper copies of meeting documentation as I can't flick between things on screen, and can't keep the info in my head).
I'm aware that I am doing all of this to appear "normal" and that I "can cope". Which I can, if I do all of this. But is it all just a mask? If I think of it as coping strategies I feel in control, but if I think of it as masking I feel a failure.
I also have to "mask" when I am out in company, because of the stuff I talk about.
