What you don't realize is YOU CAN take a break from all of that. The world will still be here when you get back.
I bet no one cares as much about all that as you do. You are the one putting most of the pressure on yourself. Tell the boss you have to have a break. But plan it, so you don't spend it on family or issues like that... and make sure you have support of some type so you don't spend that time worrying about the things you think you should be doing.
I had to learn a different perspective. I went from being on top of the world to being unable to do nearly anything (at the time.) I found out a whole lot of what can go on the back burner, and what can just be tossed.
