Going to jail might just save her life, rather than ruin it. God's blessings come strangely wrapped sometimes, but my guess is that this whole experience with her is a blessing in disguise.
I know your worry and I can tell you, when I stopped worrying about my son (it never once changed the outcome) and started taking care of myself by going to meetings and working my own program...my life became worth living again.
Sending lots of hugs and a map to the nearest meeting
