What do the song lyrics for Burnin' for You mean?

Question

Home in the valley

Home in the city

Home isn't pretty

Ain't no home for me

Home in the darkness

Home on the highway

Home isn't my way

Home I'll never be

Burn out the day

Burn out the night

I can't see no reason to put up a fight

I'm living for givin' the devil his due

And I'm burnin', I'm burnin', I'm burnin' for you

I'm burnin', I'm burnin', I'm burnin' for you

Time is the essence

Time is the season

Time ain't no reason

Got no time to slow

Time everlasting

Time to play B-sides

Time ain't on my side

Time I'll never know

Burn out the day

Burn out the night

I'm not the one to tell you what's wrong and what's right

I've seen suns that were freezing and lives that were through

But I'm burnin', I'm burnin', I'm burnin' for you

I'm burnin', I'm burnin', I'm burnin' for you

Burn out the day

Burn out the night

I can't see no reason to put up a fight

I'm living for givin' the devil his due

And I'm burnin', I'm burnin', I'm burnin' for you

I'm burnin'

Answer 1

He's on the road, and longing for his girlfriend.

However, he probably did something that ended their relationship, but he can't get over it.

Answer 2

Either suffering for someone or longing for them.  Doesn't look like a very positive song so it's probably suffering.
