My kid sister has a serious addiction to party drugs. At first, I thought it was just an experimental phase that most rebellious teenagers go through, but I'm starting to regret thinking that. I've caught her stealing money from myself, as well as other family members in order to fuel her growing addiction. She's disappeared from home for days at a time, without any sign of where she is. At this point, I'm fearing for her wellbeing as she's beginning to access more hardcore drugs, and even participating in their usage without a social setting. As I see it, this is where things need to be stopped before her entire life is ruined. I've become increasingly angry with her and at points, I think she deserves this. Any attempts to be kind and supportive to her have backfired. I used to care for her so much, but recently I find myself loathing her. Question is, how can I help and when do I need to step back?
