We are at my grandparents cottage  for the weekend. I woke up to sounds of running around and I see that my sister is in her room throwing up. She admitted she drank vodka shots. She is 15. My grandma found out and is going to tell our mom. Im worried for both my sister right now who currently is drunk and suicidal and I want to call my mom but my grandma is not letting me do so because she doesn’t want my mom to be woken up. I can’t sleep.  Im shaking because I’m so anxious, and worried my parents will blame me and kick me out. But I was sleeping and didn’t even know. Didn’t know my sister has depression. I feel like a terrible sister for not letting her vent to me right now but I’m having panic attacks and I literally cannot function. Not sure what to do, I just want her to be helped but I’m not a therapist. She told me she drank because she couldn’t take it anymore. Obviously She needs to seek mental help. Sadly I live in a very dysfunctional family, that blames you for being depressed , or anxious (in my case). I’m mentally okay but right now, I feel like I’m going to have a heart attack because my sister made a very bad decision. Unsure of what to do, how to cope. I need sleep but how can one sleep in this position.
