Do you have a senior center that is near you? I know when I had surgery they had a service that delivers meals. It was very inexpensive. Are you on a medicare plan? Sometimes they offer services to help. I don't know your age but maybe something similar could help you.
You could hire a cleaning lady to keep your place clean. As far as grocery shopping, maybe one of your neighbors could help. I know some grocery stores have plans you join and they will deliver your food. Their are many options to help until you can manage on your own. Just a few suggestions you might use. Wishing you good health going forward.
