Emotions about ARFID

How do you cope with the anger,resentment, frustration, and depression that comes with having ARFID? I’m in the process of getting a tube and I’m struggling a lot. I have many signs of malnutrition. I’m exhausted all the time. I see other people just pop food in their mouths like it’s no big deal and they don’t give it a second thought. ARFID is ruining my life and I’m having a lot of big feelings about it.
