I was watching this video and one of the guys being interviewed hit the nail on the head.
He called his eating disorder a roommate in his head and he’s just trying to ask it to be less messy.
That’s exactly it.
It sounds absurd that the mind can be so powerful, but the mind really is incredibly persuasive. To have constant noise or a voice in your head that you know shouldn’t be there is a battle that someone with an Eating Disorder fights every single day.
