I'm sharing a poem that expresses the feeling of having GVHD, as a result of a stem cell transplant with my brother as my donor:

Genetically Modified Organism 
one part of me does not like the others
senses a separate origin elsewhere 
hurts what hinders 
its self-expression 
saws at the quick of my fingernails 
has a bitter distaste for my tongue 
drops hints of distemper into my liver 
leaves faint-inducing traces of arsenic in my kidneys 
hates my guts with a torrid passion 
keeps me safe from a still worse enemy 
knows I depend on its hostility 
loves me in spite of everything 
like an envious younger brother who plots his revenge through a two-way mirror 
and watches me where I blindly suffer 
the life-giving adrenaline of his anger
