"Painkiller" lyrics

I've been talking to my therapist for six months now
Tryna unpack everything, the why, what, how
I could've ever messed it up so bad, it hurts
You were the only one I've ever been my real self with
You were my rock, my safety net when things got shit
You were my painkiller for so long
You righted so many wrongs

Oh, I thought you loved me enough to forgive mistakes and
Where did that side of you go?
Where's the give and taking?

'Cause you walked away so easy
You gave up without a fight
I know, I'm the one who messed up
But I still have a right
To demand a little more of you
I can't believe you wouldn't talk things through
And now I'm left to re-build all the parts of me that you left behind
And now I'm left to re-build all the parts of me that you left behind

I've been sleeping late and eating bad for six months now
Overthinking every little thing, the why, what, how
You could've gone and disappeared like that, it hurts
And just admit you didn't take on any ownership
I know I lost my grip
But it takes two to drift
Been on the painkillers for so long
That they don't even work now

Oh, I thought you loved me enough to forgive mistakes and
Where did that side of you go
Where's the give and taking?

'Cause you walked away so easy
You gave up without a fight
I know, I'm the one who messed up
But I still have a right
To demand a little more of you
I can't believe you wouldn't talk things through
And now I'm left to re-build all the parts of me that you left behind
And now I'm left to re-build all the parts of me that you left behind
