My parents are recently divorced and let's just say it didn't end peacefully. There was lots of yelling. Confessions. Etc. My dad tried committing suicide when he was still married to my mom. My mom started drinking again. I'm not worriedabout myself because I know how to take care of myself and deal with things the way I need to.

Recently, my sister turned to drugs and alcohol. She tells me all these horrifying stories about it. Like just a couple of days ago, she was doing air-duster with a friend and she, later, woke up, not knowing what had happened. I'm a wreck always wondering where she is and what she's doing. Even though I am younger than her, I still worry. She tells me she doesn't want help and she knows her limits. I'm always scared she's going to overdose and she's going to kill heself. I told her that and she keeps telling me not to worry.

I don't know what to do any more and I'm scared out of my eyeballs aout this.

With the drugs, it's hard to help someone that does not want it. I used to refuse help from people until one day I woke and realized that I can't keep doing what I am doing if I wanted to live.

Try to keep her busy and away from the people doing it. Huffing actually doesn't make you "high" it actually cuts off oxygen to your brain which is why you get the "high" feeling. I would try sitting her down and explaining to her that she is your sister and you really care what happens to her and explain what huffing does.

Hopefully things work out for you.

She knows all this. She know How scared I am. She's older than me so I can't really tell her what to do since she's turning 18 soon. She knows what all of this does to her. She says this is how she deals with things that have happened like a good cryor binging helps you deal with stuff. It;s not healthy and she knows every bit of this, but she still won't stop and doesn't want to be taken to a doctor.

You do have a serious problem out there EmoMarionette. Im sad about what happened to your family especially to your sister.
It's hard for you since your younger than her, why not ask a close friends whom she trust the most and ask her/him if they could help you in making your sister stop from all the things she have been doing. They might become a bit of a help.

It might, but you see, all of her friends are the ones who turned her to it. Whenever I tell my best friend about it, she always says "Jeez you're sister is so dumb." That doesn't help me much. I mean yes her decision was dumb, but no one ever asks me if I'm okay with it. I'm not. I'm really not. What I don't understand is that my mom is okay with it. Just as long she doesn't do it in the house. Yet my mom wasn't okay with the way I was dealing with things and I had to be taken to get help whether I wanted to or not. I'm not saying that I should be getting fair treatment. I'm saying that my sister should be taken to get help, but my mom says not unless she wants it. And she'll never want it. She told me that herself.
