My applause for you recognizing the still small voice when you need it. How you got into this situation is irrelevant to the need. if you have a physical need for assistance, accept it. And I hope you can use that “driving” voice to help you with the weight loss. Swimming may be a great option for you! I suffer from chronic pain and that has created a weight issue for me. It is very hard to lose weight when pain is a barrier. But you, and I, can overcome this in baby steps and cold-hard DRIVE. My heartfelt wishes of support go out to you on your journey.
I see your spirit and wish you the BEST.
