Financial issues

Ok i would appreciate if you could take time to read this and give your opinions. Ok so when we.moved into our home 5 years ago we lived comfortably within our means. We didnt have a ton of leftover cash each month but we had a comfortable margine. Now 5 years later the cost of living has increased onsanely and the paychecks.........have not. My husband works for a company that has swing shifts and im a stay at home mom and homeschool soooooo while i am open to working part time finding a job that would work with our schedule would be hard to say the least. We do not live extravagantly. Rarely eat out have no car payments etc no credit card debit i need some suggestions on.lower our monthly expenses we are pricing new insurance options and cell phone plan reduction. Its so tough bc it 2 years time our gas has more than doubled and groceries have doubled in price. And thats with me being EXTREMELY frugal. We are just discouraged and at a loss for what to do
