I know there is a depression thread but I need all the help possible.

My 16 y0 brother last night apparently was set to take his own life. It was only his girlfriend phoning my dad telling him he'd said goodbye etc that stopped it. I am furious nobody told me, keeping fucking secrets especially ones like that isn't a matter of trust or privacy, it's bottling things up. He's got high functioning autism, and has struggled with depression for a couple of years. Doctors keep fobbing him off. He's not on any meds.

The rents are away to go on holiday for 5 days, he stays in room outside the house, anyone got any advice? I am not happy about him being out there at all but what can I do? That's his room.
