I am so sorry Lyn. I don't know why these things always seem to happen around the holidays, perhaps the extra stress. Before you say anything to your kids you need to take a day or two and calm down. You and your H should do this together and you should both agree on how to tell them.
They probably already know that things were not going so well. Take care of yourself now. Don't beat yourself up over what might have been or should have been, all you have is what is. Know that you tried and have done all that you could. hugs.
