Sorry for your News! Such a shock. The Nurses' response doesn't sound exactly supportive either
You could ring Macmillan to see what support they can offer, including a one-off payment should you have bills to pay. Your GP/Practice Nurse may well know of someone you can talk to and there are other cancer support groups, 'backup' springs to mind.
What support do you have at home? You need to know how long you will be in Hospital, what clothing to take suitable for post-surgery, how long recovery will take …….. which is what the Nurse should have talked to you about.
