Reading this I feel the need to ask you all to check with your banks whether joint accounts are frozen upon the death of the one holder.
The are in Denmark, and my understanding is that this is a principle of any country's banking systems.
In other words, if you only have joint accounts the survivor will literally be left with no access to his our her own money until Probate has been granted on the death of their spouse.
Here all married couples are advised and expected to have seperate accounts as well as any joint accounts they may wish to have.
Our state pensions can only be paid into our separate accounts as no details of anyone's income may be revealed by any authority or bank to anyone else (including a spouse)
So look into this ASAP or you may find yourself in a very unenviable position while trying to deal with the loss of your spouse.
Sorry OP! First I hope your health continues to improve. Apart from everything already suggested: do you have any magazine, newspaper, Netflix etc. subscriptions, or donations to charities that are paid by standing order? If so, you might want to put all these on stand-by until things improve financially again.
Please, do not rush back to work, or take too seriously the making food from scratch idea if you do the cooking. It is a fine one if you husband cooks, but as I am sure you are tired, or tire easily right now, it is not for you.
And if your better half can't do housework now is the time for him to learn, or else just let it pile up, until you feel like doing it.
