It’s from a longer poem (the rest of which, although it’s remarkably well-written and painful to read, doesn’t chime a Doctor/Rose bell with me); this particular part, borrowed from the last stanza of the poem, makes me think of what Rose might have been thinking of for at least a little while after the events of Journey’s End.
I sometimes wonder
if you were mad at me
and if you hate me
and if this will always hurt
so numbingly much.
