Sorry to hear of the troubles you are facing. IMO a 16 year old doesn't know what he/she wants, and certainly not what he/she needs! You are the parent and have to make the adult decision here. These feelings don't go away by themselves, now do they? They are caused by something, and suicide is improper coping. Remember depression causes us to think illogically. Medication helps many to begin thinking logically again. Make the call now!
