Hi jmo,
IMHO your body is telling you to take a break, and let some of the pressure go.
I don't know why we always feel so guilty for being ill, it makes no sense, but we do it to ourselves all the time.
It might take a little time, but I think things will work out for you. It's just about letting go of the crap and moving into a new part of our lives. It really can happen!
Good luck, Myzen
