I am so sorry that this is happening to you. So many have been affected. I was recruited to and was in the middle of setting up a new product for a company and they pulled the plans after only a few months!! So I had a few frustrating months at home. Wish I had relaxed a bit more about it. here are my (lengthy) tips:
-Exercise together- jogging, walking, playing tennis. Very good in lots of ways: sleep, endorphins.
-Play more favourite music at home
-Help someone who is struggling- will you both put your troubles in perspective
-Have more sex; it is very good for bonding, releasing endorphins
-Fix things round the house that you haven't been able to fix when you were busy
-Not sure how much money you need to get by but consider giving tutoring to pay for the groceries see link
-Not sure how much cash/savings you have tucked away but you could consider allocating a small portion for starting business or investing. When I was off work I did a bit of day trading but you have to allocate a certain amount of capital for this and not be a stress bunny or addictive. Best not to "play in large size". I played the fx market for couple of hours and it helped to keep me plugged connected to the world. Can give your DH's sense of purpose.
-Help your local MP do some community work. Many of them have lots of volunteers but they always welcome help with campaigning if your MPs politics is aligned with your DH.
-When I was off work, once or twice a week I picked up 3 children of very busy friends from school. They played with my three whilst I made dinner for them. Worked out quite well and made me feel like I was helping someone.
-DH should go out for coffee with his network . Don't ask for a job- ask for career advice/ pointers. Stay positive, people are very attracted to that.
-DH should imagine himself in his own movie: "so the chips are down. what do I do?".
-DH should see it this way: he is taking a couple of his retirement years early in life when he is still young. Can always work a coiuple of years longer when he is older. Have fun now.
-All very difficult to do but it is a mind vattle. Most of all remember that we are all in the elite 1pc of the world's population! really what is the worst that will happen? He will not go hungry, will have somewhere to live.....
