Guilty of stealing

Lately I have been feeling guilty because I started “stealing” certain items especially at Walmart at self checkout. I pay for most of my items but I’ll pretend i didn’t see like 4 other items in my cart. I feel like I have fallen into stress because I’m a home at stay mom with 3 toddlers my husband is the only one who has income and theirs times where I see him get stressed out over the money. And i have told him I’ll work and get a second income he says no because we would spend more on daycare. Idk what else to do I’m scared I’ll get arrested or in trouble. I’m stressed how everything here in CA food is so expensive clothes for winter has been tripe the price feels like you can’t buy anything like before anymore. He already pays for everything and I’m here wanting to do something to help I’m scared to get arrested or get caught or what if they know or something idk idk what else to do 😔☹️
