I get nervous in cars

You said this time would be the last
You said that it's over
You swore to me you'd put the bottle back down
So many times I've tried to teach you
To keep you from losing another one
Cause she can see right through all the excuses you
feed her
And I know that I can't find any kind of definition
Cause you seem so dead to me
Do you still ask yourself "Will they remember me?"
Do you still ask your self "Why do I even try?"
Cause we'd die fighting to keep you alive
You said so softly to me once while waiting for her
You've got so much
You know son
You've got the world on your shoulders
So carry me home
I know it won't change, no it won't change
It won't go away
And I can't bare to watch you do this to yourself
another time
You said that it's over
I can't believe you'd ever lie to her
Why?
So many times I've tried to teach you
To keep you from losing her again
