Teressa's needle

I am Teressa's needle,
 I am there for her when she's sick,
She looks to me when she needs a rest,
She's in treatment now,
But I am still Teressa's needle.

I sit in the shadows and wait,
Watching as my kid brother is used by her boyfriend,
I watch the little ones with an enticing feeling,
Will they be like her?
I'm not sure but I want more,
I am Teressa's needle.

The problem with my situation is that treatment is taking over,
Teressa wants to be clean,
Running from me is a dumb choice,
I have already infected her,
With the contents of my syringe I have made her dependent,
She is my slave,
I am Teressa's needle.

She's weak without me,
Sick,
Tired,
Suffering,
I am Teressa's needle.
