So, time to think of you, Gro.
These feelings are a normal reaction to a horrific situation. My son's been gravely ill a few times, and, bed-sitting can just nurture despair. I get it.
Who is Mr Gro's named nurse? Ask them for contact with Family Support. There will be an organisation/department within the hospital who can help you.
You are needed. He is needed. He needs you to take all this need and manage it. That's really, really shit and really, really hard. So, get help.
Go and do it now. Go on. Who's on the ward?
Grab the friendly one (there's always one) and say "I can't do this". Tears are good at that point. MAKE them listen to you, be frank and clear and try not to be angry with them, just with the situation.
OR
Tell someone that's friends or family. Get them to speak to the ward staff and start the process of getting the help that's available, but, only those who shout ask get it.
Goodness, PM me where you are and I'll phone the consultant's secretary tomorrow and tell them "Mrs Gro needs some support".
I understand what you are saying about bedside manners, and second what's already been said. If your job is to deliver The Worst News you need to be very clear. Empathy is something you'll get from other sources. Oh look, like US!
Mr Gro needs you. Your child needs you and your bump needs you. And, now, you've got an army of MNrs who all need to will you on too.
I'll be checking back in a mo. If you haven't 1. had some fresh air 2. had a bloody good cry or 3. told someone how you feel then I Shall Get Strict With You.
Go on. Tell them. You're not the first, you, sadly, won't be the last. They haven't asked because they are run off their feet and you seem to be managing. Go on. Tell them.
