I am a 58 year old, recently widowed after 37 years of marriage. I was my dear husbands full time caregiver for the last 10 years. It's time to remember how to take care of myself. I'm extremely obese with a lot of unhealthy belly fat. I've made some feeble first steps: buying healthier food and doing "chair exercises". I realize I need a solid plan. This is my new start, my "newmoon". Suggestions?
