Trying to conceive for first time after struggling with an eating disorder for 18 years.

Is there anyone out there that struggled with an eating disorder for years and was able to get pregnant? How did you whether the natural body changes, stick to a well balanced diet, exercise in moderation, etc? I feel like a horrible perks for continuing to struggle.  I want to be happy and healthy and start a family. Any tips, feedback, or encouragement would be greatly appreciated. Thanks.
