All in all in all is all

Upon the sea, I'll catch you
Cos I have warmed to thoughts of dragging you down with me
A vessel sails inside of me
A toothed wheel listlessly
Metal heart, my mettle part
All in all
Heart strings pull like lead weights down on my chest
My pulse is racing
Please tear up the planks I surrender myself

My heart melts like a metal before it sinks to my core
I can try to remember if I felt this before
My core falls to the floor
Beneath the floorboards evermore
