I, too, am dealing with this situation. There must be something about 23 year old heroin addicts! She has stolen sooooo much from us as well as having sold everything she has. We've become smarter about keeping our possessions safe. We are working on our boundaries as she is in counseling, working, has lost custody of her son so we don't have to worry anymore about his safety. I'm in recovery myself so it is easier in some ways to understand what is going on with her. She is not in a place at the moment that she wants to help herself. She just wants to feel better, detox, eat, take a shower, and she is back at it again. I want to keep her alive but I'm starting to realize that may not happen. I'm in counseling myself. My partner isn't. I'm learning how to take care of myself. I hope you find some support too
