Of course you did the right thing by not bailing her out. Your daughter is a very sick woman who is completely controlled by her addictions at this time. Maybe a little jail time would sober her up & clear her head. I think craftlady's suggestion for you to see a lawyer about getting custody of Jenna is very sensible one. Your daughter will not be fit to care for her for a very long time, possibly years. She needs some serious intervention if she is going to ever get her life on the right track.
For your sake, please realize Amy Beth's drug/alcohol problem is not your fault. Thank God that you are there to pick up the pieces. lots of hugs & prayers going out for you.
