Lost, If you read the mlc resources, you will see that many of them have sickness throughout the crisis. Some of the sickness is very real and some of it is depression oriented. When they are this depressed, sickness tends to come front and center for them. As for work, it's going to take a long time for that "drive" to get back into gear to go back to work.
The only stable thing in his life is taking care of the finances for you the girls right now. Some of them continue to take care of the finances throughout the entire crisis. Sting (an old time poster) whose husband is still out there, continues to take care of her mortgage every month w/o fail.
I strongly urge you to take the time and read the mlc resources. The questions you have posed are all there in black and white and some of your "panic" will be soothed when you discover that all of what he is doing is very, very normal for his right now.
