Me again......I get/understand this one too. What keeps me awake at night is things going around and around and around and around in my mind with no resolution - questions to ask, things that aren't right, things I should be doing - or not, things DH has said or meant or must have and so on and so on and so on and on and on.........what helps me is getting up and writing it all down - it doesn't matter how or if no-one reads it or whatever but at the end of it, I can sleep
