Lyrics:

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]
It's 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 wen't wrong
If you only knew
How I refuse to let you go,
Even when you're gone
I don't regret any days I
Spent, nights we shared,
Or letters that I sent

[Chorus]
It's 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
I still hold onto the letters
You returned
You help me live and learn

[Chorus]
It's 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, believe in is you
I still believe in you
Oh, if you only knew
