I’d like someone 1 day a week to do laundry and grocery shopping. Possible?

Dorhill, depending on where you live you can get food shopping on line and delivered or curbside pickup.
Call your larger grocery and inquire. Or look online for their website.

Some companion services will assist in doing this and more.
some will shop for you and others will take you and assist you with your shopping.

If you have a church family - make them aware of your needs.

If not, contact a local church. Many times Deacons and youth groups are looking to help neighbors.

Hope this helps.

Do you have the home care services company Visiting Angels in your area? They might be of help.
