Well Janie, I'm fried too, but physically. Since yesterday afternoon my bowel has been obstructed by something I shouldn't have eaten but didn't realize it at the time. Which means I'm getting just as little done as you are but with much less guilt.

All the above advice is right on, clearly given by people who have been there! I hope you're not past being able to take some of it. You do realize it only gets worse if you don't change something, right? I'm put in mind of the saying about doing the same thing over and over and expecting a different result. All the best!
