I Hurt hurt hurt

Will you learn?

What if this car ride is the end
What if this cut is too deep
And you never thought to say goodbye
What if this attempt out of your hundreds kill you
What if this is too much powder
Would you confess to every lie?
Or what if you starve too much
Cut too many calories
To a place you could never return
Will you learn from me telling you
Please before it's too late?
