I feel your pain sister! I have 2 sisters that are on heroin. One is 23, the other is 18 and just gave birth last week 6wks early. Baby is tiny and going through withdrawals. My parents have never been there, so I'm there. Its extremely hard to watch someone waste away. The older sister has overdosed over a dozen times, and she also prostitutes. I am going to counseling as I just can't cope with the pain and guilt, because I raised them (both parents are alcoholics) I just know somewhere inside they are my sisters and I can't separate that from the addict. Sadly I don't have advice, just praying that they realize how wonderful they're life could be without the constant lying, stealing, manipulation etc...love and hugs your way. Here if u need to talk
