It's kind of a sinking spiral, which came first? The lack of appetite or depression? I had the same issues when I started on this merry go round and found they both had to be treated together to make progress. When I'm depressed I just don't think about food and once I get food deprived it deepens the depression. I found it most helpful to be inpatient where they had understanding of both issues and could remind me to eat small healthy snacks without pushing the guilt buttons. Personally I didn't like the eating disorder units because all I thought about then was food and it seemed to increase my fears. But that's me. You just need to find out what will work best for you.
