Here Without You- 3 Doors Down analysis?

I need a little help analyzing this song for english class. I need to annotate it for literary elements and meaning (theme) and create a thesis.

along with the music video and how it symbolizes the lyrics and meaning of the song.

A hundred days have made me older
Since the last time that I saw your pretty face
A thousand lies have made me colder
And I don’t think I can look at this the same
But all the miles that separate
Disappear now when I’m dreaming of your face

I’m here without you baby
But you’re still on my lonely mind
I think about you baby
And I dream about you all the time
I’m here without you baby
But you’re still with me in my dreams
And tonight it’s only you and me

The miles just keep rollin’
As the people leave their way to say hello
I’ve heard this life is overrated
But I hope that it gets better as we go

I’m here without you baby
But you’re still on my lonely mind
I think about you baby
And I dream about you all the time
I’m here without you baby
But you’re still with me in my dreams
And tonight girl its only you and me

Everything I know, and anywhere I go
It gets hard but it wont take away my love
And when the last one falls
When it’s all said and done
It gets hard but it wont take away my love

I’m here without you baby
But you’re still on my lonely mind
I think about you baby
And I dream about you all the time
I’m here without you baby
But you’re still with me in my dreams
And tonight girl its only you and me
