This could jsut be a phase that will not develop into a full ED, but it could go further indeed. It's good tha tyou're concerned now that you've only done unhealthy eating for a short while. Can you say why you've been eating so little? Is it because you don't feel comfortable with your body, because you want to be skinnier, or is it something about the food tha tyou despise? Figuring out why you restrict is the first step in replacing it with alternatives that are healthier. If you feel like talking about this, feel free to. I have had issues with food for about six months but they haven't developed into a full ED.
