I am so sorry for your loss! You can go to "your shop..." page in the upper right of your browser and then click on "shop options" on the left. Click on Vacation mode and turn it on. Your listings will be saved but noone can see or buy them. When you go off vacation mode your listings will be there.
I am so so sorry to hear that Dorothy. I agree with Patricia, I would put your shop on vacation mode and then when you are ready you can remove this and your shop will be like how you left it.
Dorothy I am so sorry! My sympathies and prayers go out to you. I agree with the above shops to go in vacation mode. When you feel ready you can open it back up and it may help you keep focused through your difficult time. (((Hugs)))
If you don't want to do the full vacation mode you can use Betsi Lite app to put an announcement on each listing. It will bulk edit for you. Than you can out an announcement on your home page. I have done this 3 times for a week+ each time.
May your heart heal quickly in this sad time for you.
