You should be able to document your income, expenses, and (hopefully) savings every month. If your income minus expenses is a positive number, you can relax a little. You still may want to work on your budget so you can save more for an emergency or retirement. If that number comes out negative, you could be in big trouble. Spending more money than you make means you must rely on credit. In turn, this means you are setting yourself up for more trouble because those credit card payments will get higher every month.
You can easily create your own budgeting worksheets by accessing free worksheets online and then customizing them to your specific needs. This is one area where you definitely don't need to pay money unless, of course, they come with a software program you purchase. However, if you just want to make a list of your income and expenses that you will use to create a budget then you can find plenty of free examples online.
