@OP - You asked what I'd suggest you do and this is it. Get a full-time paying job. It doesn't even have to be a good one or in healthcare. But get a full-time job; move out of your parent's house (if that's where you're living), and stand independently on your own two feet. Show that you can do this while also doing other things such as volunteering in the community. Volunteer to help a group of people you care deeply for -- perhaps young women, and dive in.
I would absolutely want to know if your anorexia admission from AMCAS #1 will be discoverable. If it is - own it. (Is it possible one of your LORs mentioned it?) Tell your own story your way and incorporate it into your narrative as part of who you once were and what you went through to become the strong and healthy person you are today. If your history is discoverable or you decide to disclose, do something related to anorexia, body dysmorphic disorders and body positivity, cyber-bullying -- things that torture teens.
If it's not discoverable, then recognize that your last 10 years look kind of like a sponge, and you'll have to do some fancy tap-dancing if you don't want to disclose.
I'm firmly anti-stigma and believe in second chances; but I'm also a realist. A history of anorexia makes you a high-risk applicant. You'll have to choose whether to disclose or not, and play that hand to the best of your ability.
Good Luck to you --
