@Catherine883,
First off, my thoughts are with you as you deal with the canceer. Hope that you are kept as comfortable and pain free as possible.
As to your employer, ignore their ridiculous idea of selling off everything. As you have indicated, you'll still need a bed and dishes, cooking vessels, eating utensils and likely many other things as well.
You may be able to find a furnished apartment, at which time you can decide if you want to sell off your belongings. Additionally, talk with your daughter, there may be a piece or more of furniture which has some sentimental value to her.
Regarding your mother's ashes, I am at a loss to how those would be sold. You should however discuss with your daughter or any other family member, what to do with them if you do not survive. It may be against the law to sell the cremains. You would have to check the laws in your area.
