ilpds,

Many of us have gone through the same problem. My wife would notice me in that state and take my hand and leave. It was common when out is a busy public environment. I rarely have these episodes anymore but it was a few years before they went away. Now, if they happen, they are not as deep, meaning I can break out by myself in most cases.

Having someone near who understand is helpful. Be sure to be open about these with your family. My wife used to think I was lost in thought when I was just lost in my mind. I explained this and she learned to ask if I was OK.

My best to you.
