I went to visit my colleagues today.  I am comfortable being retired at the moment.  I was rather dreading going back - I worked from January to April after Lisa died.  I look back and wonder what I did.  I recall so little.  It was good to hear the new manager say that the staff have told her how good I was.  I guess I must have done something positive!
I know that they helped me through the absolute worst time of my life.  I will always be grateful to them for the support I got when I went back to work.
