Good idea but it will most likely create far more problems than solve any.

People will likely get more overwhelmed mentally discussing the emotional/psychological impact of a serious diagnosis with a third party apart from the specialist. 

It will even be worse if that service exists apart from the mental health service too.

So that will mean for a person with new cancer diagnosis for example- they will talk to oncologist, cancer nurse, gp, mental health service and then an emotional burden support worker. 

In my view all of this will lead to an unnecessary information overload that will be counterproductive and cause far more problems.

The system as it is, works fine, if people actually maximise all the existing services. There’s already a lot of charities that provide these “emotion burden” support services like dementia uk for dementia patients and diabetes uk for diabetes patients etc etc
