He's 19. He started uni in sept. I thought everything was going well. He's been depressed for years, suicidal for months. He's been under the crisis team. He appeared at our doorstep this afternoon. He's come home to try and stay safe. He took 30 paracetamol sat night and his flatmates took him to a&e. This is the first we have heard of it. He didn't want us to be told. I don't know where to go from here. Uni have sent him home for a few days. I just don't know what to do anymore I don't know how to keep him safe. This time there was no warning, no incident that precipitated it. It came out of nowhere and that what's worrying him and is the most. What do we do now?
