I myself have 15 years recovery from an Eating Disorder; not
Anorexia, but I have spoken with many
people who have longterm recovery from that as well. Over time, your symptoms will get less and less frequent and when you are in recovery if something upsets you you will think about restricting, but will have other tools to handle your feelings.
I think it is very much important for you to receive treatment for your Anorexia because it is very very hard to do it on your own.
