My brother's mental health is really concerning me. He's a grown man so I'm aware there's not a lot I can do, but he's smoking and drinking himself into oblivion. He recently asked me a question about suicide which of course terrified me because why is that on his brain? He's had a psychotic break before and didn't get any kind of aftercare after. I can see he's either about to have another one or it's going to end in suicide. What can I do? I can't just get him sectioned can I? I'm so worried. Any advice would be great, thank you.
