Last Seconds Missing

But what’s every breath without you,
And one more second ill push through

But it won’t be the same
No wont be the same

You’ve taken a part of me that I can’t replace,
And I can’t forget the look on your face
As you ended this
As you ended this

I watch the tree we used to sit by
Stare at the stars way up in the sky

Oh but it’s not the same
It’ll never be the same

You’ve taken a part of me that I can’t replace,
And I can’t forget the look on your face
As you ended this (ooh)
As you ended this (whoa ooh)

What did u expect?
How am I meant to forget?
Every detail
Every moment
Every time you made my heart thump

You’ve broken me
Taken me from heaven to hell
Broken me,
There’s nothing I can be
Because

You’ve taken a part of me that I can’t replace,
And I can’t forget the look on your face
As you ended this
As you ended this (whoa)
As you ended thissss dream

These lyrics could be really good however I'm unsure about your opening line, it just doesn't seem like a way of opening a song, it's too random, however I feel the rest of your lyrics are written well. I would re-arrange it to be:

I watch the tree we used to sit by
Stare at the stars way up in the sky

Oh but it’s not the same
It’ll never be the same

You’ve taken a part of me that I can’t replace,
And I can’t forget the look on your face
As you ended this
As you ended this

But what’s every breath without you,
And one more second I'll push through

But it won’t be the same
No wont be the same

You’ve taken a part of me that I can’t replace,
And I can’t forget the look on your face
As you ended this (ooh)
As you ended this (whoa ooh)

What did u expect?
How am I meant to forget?
Every detail
Every moment
Every time you made my heart thump

You’ve broken me
Taken me from heaven to hell
Broken me,
There’s nothing I can be
Because

You’ve taken a part of me that I can’t replace,
And I can’t forget the look on your face
As you ended this
As you ended this (whoa)
As you ended thissss dream

I hope this has helped!
