If you only knew   I'm hanging by a thread   The web I spin for you   If you only knew   I'd sacrifice my beating heart   Before I lose you      I still hold onto the letters you returned   I swear I've lived and learned      [Chorus]   Its 4:03 and I can't sleep   Without you next to me   I toss and turn like the sea   If I drown tonight   Bring me back to life   Breathe your breath in me   The only thing that I still believe in is you   If you only knew      If you only knew   How many times I counted    All the words that went wrong   If you only knew   How I refuse to let you go   Even though you're gone      I don't regret any days I spent   Nights we shared   Or letters than I sent      [Chorus]      I still hold onto the letters you returned   You helped me live and learn      [Chorus]
