When I was "really" bad I had "ana" and "mia" as two separate entities. "Ana" would scream at me when I ate. "Mia" would calm me and "her" by reminding "us" I could purge. Right now I don't see "them" as separate. I can't say what's healthier. I feel healthier without the names but currently I'm kicking, biting, hitting, and clawing while I'm chemically being dragged towards recovery.
