This addiction

My breath is growing weak
My skin is turning yellow
My lungs... there failing
I may be dying
People think I don't care
I Swear I do
But I can't stop
I used to say I could
But now its growing harder to quit
My self restraint is failing
Im smoking a pack a day
is a lie
More like 3 to 4
And now I wish I'd never started
Because I don't think I can ever stop
