Glad things went well. Being hooked to tubes because you are underweight is no fun. Keep thinking positively about everything that is going to happen on Tuesday. At least you don't have to go inpatient. When I was at my lowest weight, I had to be inpatient.
It is the ED that was lying to you about your weight. Remember that it wants us to be "perfect" which for me was thin. Ana loves to lie about a lot of things about us just to keep her in the forefront of our minds. Let us know how Tuesday goes.
