[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
