You expect me to do what? How?

So, I have now had two medical professionals flat out tell me I need to make a change - actively find a way to reduce stress.  Counselor wants me to take more time off work.  Chiropractor says I need to reduce my stress at work...and if my shoulder doesn't start getting better I will need to do physical therapy.  Oh goody.  And how exactly am I supposed to reduce my stress?
Well, first my boss and I are working out who my backups are for different things I do.  I took a day and a half off...and have been paying for it dearly.  Still trying to catch up with everything.  I might have caught up with most of last week today.
The idea is that with stress reduced I'll sleep better and if I sleep better, I'll stress less, and around and around she goes.  And where she stops?  I guess we'll find out.
