Pretnja samoubistvom predoziranjem benzodiazepinima i alkoholom

Greetings to the doctor! I\'m temporary in Serbia with my Serbian husband and he fell into depression and he threatened me he\'ll commit a suicide by overdosing with benzos and alcohol. I\'m extremely worried and he\'s hospitalized but he said when he get out he will take certain meds and he hide his pills. I will say what he said he has. Valium 3 packs =150mg, Xanas 1 pack 15mg, klonpin 3 packs = 180mg, ambien 600mg and midazolam 150mg. He said he\'ll take all this with vodka. I\'m worried how these pills are really dangerous and is it possible to die if he overdose. Thank you very much. Happy holidays
