Liver: I am totally with you! It's something I'd like to be able to eat because it has nutrition, but... yeah it's still on the list of horrors. Many things are.

Veggies: there are still some that give me the horrors, but it's really all in the cooking (and the seasoning). Which is not to say I am a good cook.

I hope over time you find a bit more enjoyment from food but I do fully understand where you are, and very often I am reminded that I could end up back there.

(When I was a kid, early '80s, my mother, exasperated, took me to the doctor and said, he only eats (lists three things). The enlightened doctor said to my mother, in front of me, and I quote: "That sounds lovely. Invite me round for Sunday lunch". And then to my mother when I was not in the room, that worrying about my intake and pushing me to eat things would only make it worse for me.)
