Shinedown - if you only knew

해석 부탁 드립니다. 번역기말구 의역으루요~!!!!!

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
