Being sick to me means:

an association with my past
having to ask for help
watching bad tv during the day
frustration
feeling cut off from the world
taking pain killers (something i never do)
being unproductive
loss of interest in food
not sleeping properly
drinking sports drinks
boredom
feeling yucky
forcing myself to eat/drink
pain
longing for someone (to look after me)
the longest days/nights
feeling hot in the middle of winter

did i mention being pessimistic?
