"Let You Down" lyrics

My hate for you is pure self-defense
I knew I'd lose you from my selfishness
The pain I feel for pushing you away
My world's colors have turned grey

Tired, I can't sleep
Hoping, I won't let you down
Down

I lie awake, full of such regret
I try in vain, but there's nothing left
I think of you, and fill with self-contempt
I wish we could just press reset

Tired, I can't sleep
Hoping, I won't let you down
Down

Go, I just know, you're better off without me
I just let you down (Better off without me)
(Better off with-)
I just let you down

Down, down, down, down
