Help finding a job

I need help. My husband works in the hospital full time. And just finding a regular job has been hard because he works crazy hours and random days. He doesn’t have a set schedule. I worked at Walmart for a few months but they gave me problems. They were fine with the schedule at first. But after a few weeks the manager she mad that I didn’t have a set schedule. I told them that I can only work certain days because of my husbands schedule and I also don’t have anyone to watch our son. So I worked until they fired me. I’ve been looking for things to do for work but I can’t find anything that’s remote. Please does anyone have any suggestions?
