[Verse 1]
I was built for self-destruction
My heart needs these chemicals to function
But there's beauty nestled in these cracks that define my head
Life's hanging on by threads

[Chorus]
We were oxygen for each other's lungs
Harsh words on each other's tongues
I see myself in the mirror
I just don't want to
We we both know I let you down
We were oxygen for each other's lungs
Harsh words on each other's tongues
This is all I can handle
Even though you won't say it
We both know I let you down

[Verse 2]
I was built for self-destruction
My mind needs these chemicals to function
We burn bridges meant for brothers
And as we stare down the ashes, we smother our names

[Chorus]
We were oxygen for each other's lungs
Harsh words on each other's tongues
I see myself in the mirror
I just don't want to
We we both know I let you down
We were oxygen for each other's lungs
Harsh words on each other's tongues
This is all I can handle
Even though you won't say it
We both know I let you down
