@victoriasitko Welcome to Mayo Clinic Connect. There are several discussions about diet here in the kidney and bladder group. If you go to the main page and put "diet" without the quote marks into the search bar, you will get a list. It will be worth your time to take a look and see what others have said.

Do you know what your eGFR number is? That will be the indicator of what stage your are in. From the National Kidney Foundation, here is a good article that explains all this: https://www.kidney.org/kidney-topics/estimated-glomerular-filtration-rate-egfr

Uncontrolled diabetes or high blood pressure are the leading causes of chronic kidney disease. Also, medication side effects, genetic factors, or lifestyle choices can play a part in kidney disease. Have you and your medical team been able to determine the underlying cause?
