It seems like she has totally checked out so I am not sure if I should take a different tack.
Again she is depressed. There is nothing YOU can control to make her undepressed. If you have been controlling the last thing you want to do is to try to control her depression! That will backfire. You can be friendly but be detached. Give her space. She needs to work this out on her schedule. Not yours. This is not something that is going to get fixed fast.
When I asked if you read the resources I am trying to get through to you what this process is. How long it takes. You need patience.
