Feeding 5 people cannot be easy but nothing worth doing ever is! ;) Another key point was patience. It wasn't instantaneous. It takes some time for all the bad foods to pass and the vibrant wholesome foods to dominate your system.
Another way to save money and build confidence is to grow your own healthy fruits and veggies. This saves money and helps boost your confidence level and sense of independence. As we both know confidence and anxiety cannot coexist! Also I'm interested where you disagree with my previous statement. ;)
