My mother passes away only last year from a self inflicting overdoes. She's always had trouble through my early childhood go into rehab, getting sober, then hitting the pills again. I knew that one day this was going to kill her and I did nothing to stop it. If you or someone you know is struggling, help them. They just need someone to hang on to. That's something I did not do for my mother and I lost her at 15. One year later I'm still blaming myself for it. Don't make the same mistakes I did.
