I'm sure there are many who have gone out of their way for family members, in the hope they would get clean and sober. I, myself, had my 52 year-old heroin addicted son living with me for 10 years...and, I should have known better, since I have many years of sobriety through AA. But, it's not so easy to "detach with love"...easier said than done.
Fortunately, he went into rehab last year and recently celebrated one year of sobriety. So, it can happen for your daughter, too.
