Fatigue or Anemia?

I have been eating more but I am still far from feeling well.  A little exercise, like walking out to the chicken coop, exhausts me and my back muscles burn.  I plan to drive up to join Nancy at the lake tomorrow.  Mostly just so she won't be alone in her camp.  I offer very little chance of really helping her with boating or other endeavors.  I have begun eating apricot pits again with the possibility that I have a rumor.  It is possible I suffer from some kind of infection.  Maybe I'll recover.
