Dear Roz,
I am so sorry that you are not getting the help you need from your GP and social worker. If you feel strong enough you should pester them and make sure you have not been forgotten, this does have too often I am afraid.
Have you tried phoning Ellen at Myeloma UK? She was wonderful when Steve was first diagnosed and helped me a great deal. She may be able to suggest something for you, or as someone else has said you could try the Macmillan nurses.
I cant begin to imagine the pain and grief that you, Sara and Min are going through but I hope you know that everyone on here is there for you and will give as much support as they can.
With love Mari x
