All Wrong!!

My sister walked out, so when will things be ok.
Started January, got worst in May.
With all the sneaking and lieing, nothings right.
Begin to do drugs, and now I'm losing might.
She chose him over us, I was sad for days.
But why would she care, he was her craze.
I thought things would get better, thought it was a phase
She tried hurting herself, but didn't get far "/
She seems stuck, but she'll still take that triple-bar.
I messed up, its me fault she's like this.
I hooked them up, that's something i didn't miss.
He pulled her in, now she's gone for sometime.
But when will it end, end all of his crime.
I miss her so much, I just want the old Nesh.
But he has her, she's on his mischievous leash.
