My husband has been lucky in that he can usually sleep despite surrounding issues. While anxiety was a temporary problem in the midst of it all, he pretty much has dealt with things head on. He is able to move forward with the solutions and not dwell on what might have been. I am much worse than him about losing sleep worrying. As they say, worrying doesn't get you anywhere helpful, but it can be so very hard to shut it down. Some of us are just worriers and do it much better than others.
