Where does the Time Go?

The surgery went great and Mr. X was in the hospital 5 days.  Next we meet with the Radiologist and a Social Worker, because the radiation is not in our city and we will need a place to stay.  I am exhausted and cannot keep up with time. Today my back is spasming so bad that I could not go to work.  The stress of all of this is really affecting my body...  everyone tells me "take care of yourself or you will be of no use to him!"  Sound good... but how do you do it?
