i must have said sorry a hundred times. i'm sorry for burdening

i must have said sorry a hundred times.
i'm sorry for burdening you this much.
you won't have to put up with it much longer.
we joke around a lot and you forgave me each time.

i don't think i can forgive myself.
i don't think i can make it up to you.

just no more mistakes.
and no more second chances.

it really begs the question:
who did i think i was?
no. really, who?
