Hi Carmen,
My alcoholic sister has been drinking for 15 years now and has no plans to stop (she is 42). She has lost everything. She is living with my parents who continue to enable her. Their decision to enable her is costing them their retirement funds, peace of mind, relationship with their other adult children, and (quite possibly) their relationship together. It is a no-win situation, no matter how much they think they are "helping" her.
Your daughter is content because she has no reason to change her lifestyle; she has a roof over her head, doesn't really have to support herself, and can drink without consequences.
One thing that I've learned here and through therapy that has been tremendously helpful: actions speak louder than words, and alcoholics will not hear your words, no matter how many times you say them or beg, plead, or threaten.
I hope that you will find the strength to put yourself first. Sending you hugs.
