If you want the best advice on here, list out your debts, income and other expenses. Some people will suggest some pretty extreme things, (bankruptcy, living in a box to save the mortgage payment, walking to work etc), but often it comes down to spending habits and not having a budget. Paying off debt with more debt isn't great, but occasionally you can get lower interest rates and save some money. Generally it's better to just suck it up and pay them off if you can. Also, would really recommend having some good conversations with your partner. Finances are a joint effort, and both people need to be on board

Short term options for things saving extra money... second jobs, selling things you don't need, filling for benefits like food stamps, unemployment, Food banks, thrift stores for essentials.
