My son has never been in trouble he turned 18 last Christmas and decided to try weed. He now smokes and recently got in trouble. Problem is he was depressed prior to all this. Had ups and downs in his mood. During argument about using my car he said some very dark things against my husband and I he repeatedly kept saying he will kill himself. Things he said were very graphic. He is refusing help from a doctor, I feel lost like there's nothing we can do. What are my options? He is destroying himself and we can't do a thing. He has bouts of anger. He in hypersensitive to smell and sound.
