Track Marks & Needle Pricks

Called everyone on my phone,
Even the ones in the UK and the ones I don't know,
Ask the same question,
Each time more clearly,
My addiction is mine and I ask for it merely,
As a favor,
As a friend,
Even though it's not a trend,
I know that my dad died from this,
But inside I long for it,
Feeling nothing,
Gone insane,
Look at me,
I'm here to blame,
Track marks and needle pricks,
All my money for just one fix,
Sometimes I wish I didn't feel it,
Even when it isn't there in my arm,
I'm the one who did the harm,
Still no answer from my calls,
Am I really the one at fault?
