Ship has sailed

The saying goes
once the ship sets sail
there's no going back
well you've left harbor
and me stranded in this panic attack

i stand scared now, gasping
at the end of this metaphorical dock
id go back if i knew how, grasping
undoing the past from this lock

there's nothing i can do
but watch you race away from my life
my mind stuck on you
couldn't cut you away if i had a thousand knives

so here i am
standing helpless by the sea
watching you catch the horizon
and sail away from me.
