I'm so sorry to hear that @twistyizzy. That must have hit your DH so hard after a whole career there, and a huge worry for you both. Be gentle with yourselves.
It's utterly infuriating that there is the safety net doesn't apply to those who actually pay for it for others. In most European countries he would get short-term support linked to how much he had paid in previously, as I'm sure you know. That's what a functioning social contract looks like: fair to everyone and recognising those who have already contributed more - rather than exploitating them and giving nothing to them when it's their turn to need help.
But focus on yourselves for now, on getting through each day. Thinking of you.
