I feel that throughout my week. Sometimes my brain is just too busy with what I must self-talk about to use good communication skills. At least I believe that is why I "check out!" Sometimes it seems so trite or "surfacey" stuff. The weather, bragging about their kids, day to day mundane things and then it's like all I hear are the Charlie Brown cartoon adults... wahh wahh wahh wahhhh. I can often control it, if it is truly important what the person is saying. Maybe your inner communication is just too busy with yourself? Are you very inverted right now and dealing with so much of the PTSD that you just don't see the outside world? If you are working that hard, you may want to take a break and find something you can engage in. Just a suggestion... don't know all the pieces here I am sure!
