I've seen this shiit for years, the self harm, cutting, pulling veins out, attempted hanging on toilets\sinks, buck nekked in a denim smock, eating with paper cups etc. My clientele is obviously different than your son, but it still sucks, especially when you've never had suicidal ideation before, you don't know how they are feeling \thinking... I'm not a man of god so I don't pray, but I really hope you guys find peace...
