Contextual Analysis of "stumbling" in Lyrics

i'm scared of what i might find if i ever get behind it

stumbling block

we don't know

stumbling down

who cares we've been here so many times

it doesn't matter

i'm coming up from the grave

i'm staring over the edge

now i know that i'm

makin' a mess of it all

arm in arm

we skinned our hands

i'm

home

trembling

fumbling
