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.
