I Don't Like Who I Was Then Lyrics

Advisory - the following lyrics contain explicit language:
Tossed around like sea glass
And you rounded out my edges
I'll feel better when the headaches go away
I've got a scar across my forehead
Turning purple in the cold
From a night at Shore Memorial
I was sixteen and afraid, turned away
I'm working babyface
Out of Mid-South in the eighties
I kept a blade hidden in my wrist tape[Chorus]

I think I'm growing into someone you could trust
I want to shoulder the weight until my back breaks
I want to run until my lungs give up
If I could manage not to fuck this up
If I could manage not to fuck this up
I think enough is enoughHidden in the tall grass
In the naked light of day
Put my past self in the ground
I've been dancing on the grave
I'm not the person that I was then
I'm tearing him away
I was bitter, I was careless
I was nineteen and afraidBut you deserve more from me
Don't know why I'd say those things
But you deserve more from me
And I'm trying every day[Chorus]
I think I'm growing into someone you could trust
I want to shoulder the weight until my back breaks
I want to run until my lungs give up
If I could manage not to fuck this up
If I could manage not to fuck this up
I think enough is enoughLet me walk into circles
You were a shot in the dark
You were the baby teeth I buried
You were the sound of distant carsLet me walk into circles
You were a shot in the dark
You were the banner that says no one
That I tattooed across my heartLet me walk into circles
You were a shot in the dark
You scattered like ashes across every song that I write
You where the light pollution starts[Chorus]
I think I'm growing into someone you could trust
I want to shoulder the weight until my back breaks
I want to run until my lungs give up
If I could manage not to fuck this up
If I could manage not to fuck this up
Enough is enough
