Replying to Drugs

So the love of my life is addicted to drugs. I aint talkin like weed. I mean that to but also hard shit that can and probly will end up killin her if she don't stop. Like bad. Like bad bad. How do i help her. I told her that i was gone and she had to pick between us but then i felt awful for leaving her in her time of need. And yea it was only acouple days we didnt talk but i missed her and all she talked bout later was how bad she missed everything we had. But ive tried to help for a long time and its not doing anything, just bringing me down. I know like 100% of you are pot heads lol n dats koool just wondering if anybodys ever been through this and has good advice on what i should do and say because im outta ideas and my friends aint ever had anything like this either. Thank ns. O and if u got any real tips or anything plus k ahaha
