It may help you to think of 3 people in your life that you consider to be successful who aren't overly skinny. Success has nothing to do with weight/size, it has to do with freedom to enjoy life.
A life controlled by an ED is in no way good, meaningful or successful. It's a waste of life.

You say "I want to learn to stop enjoying food so much and focus on other things so I can have a better life", but that it a contradiction. By not worrying about the fact that you enjoy food, you will be able to focus on other things.

(If only i were able to take the advice i give so easily).

i know it's not easy though, so do all you can to challenge that ED voice.
