stressing out over groceries

So i have a large family, and most aunts and sisters live out of town, so everyone is planning different times to come and visit, some are staying couple days some are staying a couple of weeks. Great I love it, but at the same time I’m stressing about money and groceries and having enough of everything for everyone while they stay over 🤕 its like a continuous party which will need a lot of groceries, me and my husband manage just fine with ourselves and occasionally entertain but I’m more worried than excited right now. Currently couponing and trying to find deals on groceries 🤦🏽‍♀️
