I agree jail is probaby the best place for her to be in detox, esp. if she's not quite ready yet. Even if she did go to rehab those withdrawels get ya, and from what I've heard heroin (that's what she's on?) is one of the worst..
Odds of her leaving to get more were good.
I remember my meth withdrawels and don't ever want to go through that again, it's one of the reasons I won't do it again.
She's miserable right now, withdrawels won't kill you, using will. The streets will kill you, jails rarely do, they usually just make you shape up.
Someone's watching over her...
This is all a good thing. She's in a locked up place, she can't hurt herself anymore for now, no one can hurt her, she's has a pillow and a bed, sheets, a blanket, and food when she's ready, and medical care if she needs it.
AND... you know where she is....
That's a lot more than yesterday!~~ ;-)
