Well, I can tell you that losing weight is not the answer to your anxiety. I spent years anorexic and was as skinny as they come. I was more anxious than ever and more unhappy than ever. I got back to a normal weight upon recovery. Recently, I lost 35 pounds thinking that would make me happy and serene. It hasn't. I am still anxious. I think the problem lies in our thinking and not in our bodies. Trust me on this one. You will not feel better by losing weight alone. I'm not saying it might not help, but it is not a panacea. It will not cure all your woes. I would focus on helping your anxious thoughts whatever way you can.
