Recovering Anorexia! Advice please?

I have made a decision to recover from anorexia, due to recent Anemia symptoms while exercising. Plus, i've read on how unhealthy it is for the body. So i'm aware of all the health risks, and I don't want any of it. Problem is, I am terrified of gaining weight. What seems like a healthy weight to most, is like extremely obese to me. However, I have to go through with it as I already gave my word to God, and myself. I am slowly increasing my caloric intake, but am afraid I will gain weight like crazy, as my body has been in starvation mode for quite some time. I eat healthy foods, too. I am very scared of my next weigh-in. I want to be healthy and am very afraid I will go into relapse. Any advice on recovering anorexia? I want to do it so bad, I have to, its a monster inside of me. How can I get rid of this fear of food and going back to a healthy weight? Please, help me. Thanks.
