Hey Anna Maria -
One thing to be sure of, with your ED history, is that your doctor is aware of your weight and weight goals. Losing weight, even the healthy way, can trigger people with ED tendencies back into old patterns, but having a doc to supervise can help prevent that.
We have many forums here - the 20-somethings, for those in that age range, the "Chicks in Control" forum for those who struggle with disordered eating, and all kinds of groups by eating plan. Look around, find a spot or several, and settle in.
Can't wait to get to know you better!
