Feeling Helpless

Hi, I am feeling somewhat gobsmacked and helpless at the moment. My nephew, of whom I am a reluctant carer (certainly at the moment!), was admitted voluntarily to hospital yesterday and it is evident to all around him, except the specialists it seems, that he is a risk to the community and himself. I received a call this morning from him telling me that they were going to release him. I followed up with the unit and indeed it was the case. Apparently he was presenting quite rationally to them and although his medication levels were a bit low they felt he was OK to leave particularly as he was a voluntary admission.

I am amazed that specialists in the field are not able to drill down below the facade and see the manic paddling of the ducks feet below the water. (Yes I've mixed my metaphors but go with me, I'm stressed!) It is only after talking with me, which I initiated!, that they have decided to change his status to involuntary.

What resources are available to me if indeed they did release him because given his behaviour and the threats that I am receiving he is not welcome to reside here?
