Welcome back, Melanie!
A lot has happened in the past 16 years. Glad your health crisis resolved so well. There have also been many changes in the low carb world, for one, everyone calls it Keto now even if they eat no where near true Ketogenic macros. and the emphasis on real food. Whatever it is called, there are so many new books, cookbooks, and resources like DietDoctor https://www.dietdoctor.com/low-carb/keto/guides to use along with Atkins that you can explore here. Look around the various sub-forums, brush off your journal, update your profile and use this forum however best to support your journey. All the best,
