Always Been You

"Sometimes I feel like it's one-sided
Like some type of unrequited love
I keep it dark, I keep it quiet
But then you come around and light me up
Usually, I ain't the type to stay up all damn night
Thinkin' 'bout someone else
It's hard to be fine when your heart's on the line
And the truth is I'm goin' through hell
'Cause in my head
It's always been you
Heart in my hands
Hopeless 'cause no one can take it from you, you
I tried rewriting this hundreds of times
But if it ain't you, it's a lie
Yeah, in my head
It's always been you, you
I been trippin', I been slidin'
I'm underwater like Poseidon
Takin' up space like a hyphen
You're on my mind and I can't fight it, yeah
Sick of playin' games with myself
Sick of playin' like there's someone else"
