How do you know when to believe someone when they say their clean? My 29 year old daughter has been addicted to one thing or another since she was in her teens. I believed her when she told me she wasnt, but eventually found out she was lying. I guess I was just too naive to know the signs or maybe I just didn't want to believe she would do drugs. She soon got into selling perscriptions drugs and taking more drugs. Snorting and swallowing everything she could get. She is the mother of a 4 year old and 2 year old that I have basically taken care of since birth. On January 2015, we got into an argument and she attacked me. I had the kids at the time and I went and filed for temporary custody and got in right away. I have come to find out she has been into heroin and I am devastated. She needs to get clean to get the kids back and so far has gotten a job. But I have to take her to and from work ( she has no car), let her stay at me house ( she got evicted) and protect the kids. She is also bipolar, but has stopped taking her medicine. We go back to court in 2 days and she was supposed to have gotten a job, car, went to counseling, and stay clean. My question is, how do I believe she is clean? She sits and nods off all the time and sleeps all the time and blames it on being tired. I have caught her using stackers to stay awake at work. I can't believe she could give up heroin, xanax, subs just like that, without treatment. I really would like to hear from others in my situation and how I can believe shes clean when I don't feel she is telling me the truth?
