I am in the same boat. Im 5'6" and 95lbs. Getting scared too I have started eating healthy, though I find it gross to eat all day. And I cut back on my exercise like they wanted but I too am really lost. Im 42yrs old and have been anorexic since I was very young, its been 3 decades now and Im really getting afraid. Please let me know if you find anything to help and feel free to message me anytime.
Planning things out in advance, totaling the calories to make sure they're high enough, and then actually eating what I planned seems to be the only viable strategy...also ice cream...scary, yes, but it's calorie dense which means you can get a fair number of your required cals without it feeling like a lot of food.
