Journey to a better me..

I'm really trying to get back to me if that makes since in a course of three years I went from 147lbs to 203lbs factor in 2 surgeries and ectopic pregnancy and having to deal with fibromyalgia which I'm in pain every day I have started back walking as a form of exercise for now just taking it slow, but sometimes I can't help but cry when I look at old pics of myself and to think at one time I thought 147 was too much... Just need some advice that can help me on this journey
