Ruhappy, I think you are doing great with your attempts to not engage him. It's so hard to take care of ourselves when we are sad. I lost so much weight too, when it all started. Do you exercise? If you can't exercise formally, Force yourself to start walking places you normally drive, or park farther away than usual. Take the stairs instead of elevators. Start taking a walk before or after every meal. Take on projects that require physical labor -- e.g., mow the lawn of an elderly neighbor, paint your house, clean out the attic. I found that being physical helped with depression and gave me more of an appetite. Since you mentioned faith, do you know about rejoice ministries? Subscribing to those e-mails and listening to the podcasts helped me a lot because it allows you to detach through trusting God instead of just trying to change your behavior.
I believe I will see the bounty of the Lord in the land of the living. Wait for the Lord with courage. Be stouthearted, and wait for the Lord.
