I'm glad you are talking about this Bam.
I don't seem to be able to control where my head/thinking goes sometimes. Its a scary place to be and of course not haveing control is something that really drives me nuts.
I sometimes find that I get myself on track with an activity and suddenly my mind is spinning off in a direction that just adds to my stress and emotionalness...so i refocus and then it happens again...but I just keep on doing the best I can with it.
