Why is she hear?

I must confess,
her life's a mess,
Its not all her fault,
A love one died life came to a hault,
started saying stuff she didn't mean,
now shes on drugs so far from clean,
"try,try again"doesn't work here,
her life is filled with struggle and fear,
She has no clue why shes around,
After year of looking the answer is still not found,
She feels like an unwanted mut,
As she decides how deep to cut,
Suicidal thoughts run threw her head,
As the blood from her arm drips red,
"To Deep" she thinks"But i will live",
The Blade has taken her captive.
