best years by 5sos, but from the perspective of someone who lost their best years to a toxic relationship/person.

lyrics:
i've got a million reasons to hesitate
and baby, a million more are added everyday 
i spent so much of me on you i forgot who i became 
finally found a reason to walk away
the house that i built you made it a mess 
i’m left with broken pieces
can’t help how i ran out of tears

i lost all my best years
just missing my best years
past love burned out like a cigarette
i’m free now baby, all i regret
are my best years

i always felt alone when you drank too much
but still dragged you home when you cannot stand up
you meant everything to me but did i mean nothing to you?
don’t think i’ve ever known what you’re thinking of 
the house that i built you made it a mess 
i’m left with broken pieces
can’t help how i ran out of tears

i lost all my best years
just missing my best years
you burned me out like a cigarette
i'm free now baby, all i regret
are my best years

you took all my best years
you stole all my best years
robbed all my love, now i know myself
i’m free now baby, you’ll never get
my next best years
just grieving my best years

best years - rewritten

born to be the village bard, forced to post my songs on the internet

best years - rewritten
