Turning pain into purpose

I retired about five years ago and have been very busy helping family members. This area of my life has slowed down and I now have free time. I am trying to figure out what to do with the rest of my life (I am 60 years old). Your idea of turning pain into purpose appeals to me. I am finally to the point, mentally and physically, where I can do the work to figure this out. I have several food intolerances (dairy, soy, gluten, nightshades) and, using a combination of your eating program and avoiding these foods, I have lost weight, feel more focused, and have more energy and less pain.
