My parents are split up. I live with both my sisters (22 and 20) and I'm 18. My grandmother moved in with us a while ago. The reason of the move is because she used to live with my uncle but he took his own life and she found him in their cellar. The sight left her distorted in some way so we needed to take her in. You can read about it '
here'.
Since then, my mother's been doing her own thing. She doesn't stay home much anymore and is always at her boyfriend's place because she doesn't get very much time to be out of the house since she's always looking after my grandmother. So she doesn't waste any free time. As soon as someone's home with my grandmother, she takes off for the night. Sometimes she spends the night there.
Bottom line here is that we've all told my mom that her boyfriend's a bad influence. She stared smoking because of him and just yesterday, I found dietary supplements in her medicine cabinet. Not prescription but similar to those '4 hour energy shots'. They're really small. I'm really worried about her health because she's lost a lot of weight because of the combined effects of not eating as well as smoking. At first I was worried about her mental state because I thought she was going to hit a downhill but not it's affection her physical state as well and I would really like to intervene but I've never had to stop my parents, or anyone for that matter, from smoking so I don't know how to do it. I've already tried hiding her cigarettes but she doesn't care. She buys more. She doesn't yell at me asking for them because she knows I'll blast her that she shouldn't smoke.
What should I do?
