I don't have an answer for you, but I do have a prayer, coming your way. :-)
Be a mother first and the rest will follow
being a mother is not that easy , most are nurses not mothers, to be a mother is a great responsibility.
Choose your priorities.
Eating disorders should go when you decide to enjoy life, trust your body, don't treat it as if it was sick, it's your way of thinking and your fear of changing that are not right.
You just need to put the Childs healthy first and then you will be able to be healthy for her and after you can go back to your habits as long as it doesn't hurt your child..
Then you need to go get treatment
Then there's nothing let to do it never really goes away... There are bad days and good days
Okay idk how to help you...
