Newbie. Looking for healthy life change

Short story I'm new. I spent a week at mayo clinic and they ordered me a wheelchair. I was all time low. I have many medical issues and through two new changes in my life. New medication and some program called isagenex I'm hopeful for the first time in six years! In the last 12 days I've went from 279# to 267.8#. I'm walking (with cane) 12000 steps per day! Need support and positive motivation and being home bound for so long I'm nervous that with this new feeling that I may over do it! If anyone's been in situation like this it would be wonderful to touch base with for any helpful tips.
