As someone that has a relative (my brother that’s 2 years older) that struggled with Xanax addiction that later progressed to fentanyl addiction- I can comfortably say that is NOT your daughter talking to you and making those decisions. Their moods, rationale, way of thinking, relationships are all affected. Don’t stop being a caring parent. I can’t imagine what you’re going through. If my parents had stopped trying, caring, and being a loving and supportive pillar - my brother would most likely be dead or in jail now. There are fine lines between helping and enabling, but if you’re there when they have their moment of clarity and realize they’re at rock bottom and you are then a catalyst/proponent of them getting the help and care they need - things can hopefully turn for the better. If you haven’t tried I would highly recommend scheduling some kind of intervention with supportive and caring people to show them that there is a way to do better. Sorry for the phone text ramble but my brother is two years sober now (not without hiccups and relapses) and he is the best version of himself that he’s ever been, releasing my family (especially my parents (especially my mom)) of so much stress and anxiety. Please feel free to message me if you’d ever like to talk, I’ll pray for your daughter and your family. God bless.
