i think i have the opposite problem you face, i have bad anxiety and panic disorder too
i want to eat but i dont feel like eating.. i dont know if i have an ED or not, but i know that i dont eat as much as i should even though my BMI is... ok i think... eating once a day isnt normal though, and i have an upset stomach alot of the time.. but cant pull myself to eat anything, till the end of the day and i make myself eat for fear of starvation or some accidental death... i think i will bring up this EDNOS as well at my next apt, i wasnt sure what to call it to talk about it , thanks
i hope you get a handle on it
