Drugs change people, so therefore to being with she is NOT the same person, its her but changed. The best I can tell you is to have SERIOUS talk with her DO NOT baby her or feed her cycle and try your best to get her into a drug rehab a program anything of that nature, once you get addicted thats it, your in the cycle and addicted for life. This battle will now go on for the rest of her life, its one big cycle. Remember you can TRY to HELP her, but you can not change at the end of day she has to do this. I have family who I loved dear who have gone down paths that I would not have believed if I had not experienced myself. I am not saying its hopeless, but you need to approach this realistic and see it for what it is. Also just to add I don’t know what area you live in but Iam sure there are some hotline numbers or the such to help you out or least offer more advice. There is a show called Loveline with Dr.Drew you might even give the radio show a call he was did Celebrity Rehab and is a drug addiction specialist , even give it a listen for yourself you will learn some things. anyways…good luck, if anything if she has kids try to help them out there going to need it.
