How do you interpret this song?

If you can help me - english is my 3rd language so I really can't interpret all the lyrics, metaphors references from this song:

They've said it every year,
But this times it seems like the end is near and I'm in line to see the light.
How far does...

this black tunnel go?
I got a car but the gas is running low...
And as long as I've known the bumps and creeks of this house
It's starting to make the types of sounds that only comes from people's mouths.
You cant tell me it's still settling
Built on an indian burial ground killing everything
The childhood scar on my chin is back again
That old jump over my own leg dance move has to end...
I've seen better days in my night terrors
I was a bike messenger without a bike and I would write letters
Ask directions to your whereabouts
Before the slow walk the rest of the show-offs were pealing out
To many hares only one tortise
Thats why I left this city, too fast paced for this HO-HUM TAURUS
By the time I developed the pictures they're as blurry as my memory of constant life fixtures
If distance is a girl's best friend
Tell them bit*hes in the rough who think that love comes with DIAMONDS

Slave labor, you made me work for what I couldnt have
Diamonds cut, but coal burns and nothing lasts forever
Dont know why I bothered saving any of your letters,they're just aged paper
Crumbling

Slave labor, you made me work for what I couldnt have
Diamonds cut, the cold burns and nothing lasts
Wonder why I saved your urn of ashes
I've got an insecurity box for your mail
Tracing the name on the return address as if it was made of braille
Pretended it was your finger but careful to not break a nail
The one that sealed the coffin shut. When it opened caused a paper trail
But since then I buried your dead sea scrolls
And emptied my head of these old trivial memories that I seem to hold
Now you're a foot note with cement shoes
In case you wonder what that sinking feeling has been ever since I left you.

They've said it every year,
But this times it seems like the end is near and I'm in line to see the light.
How far does this black tunnel go?
I got a car but the gas is running low...- th person is becoming sick and tired of life. they have little ethusiasm and are running low on energy.

Built on an indian burial ground killing everything
The childhood scar on my chin is back again
That old jump over my own leg dance move has to end... - they're feeling deja vus. they've been here before and are reliving a nightmare. they wish it would go away. you can tell this by how they use old burial ground childhood to represent the past and death.
