MrHomerCat,
It would awfully tough for me NOT to be depressed if I were in your shoes. Heck, when I think about the world, economy, health, Earth, etc I just become overwhelmed by great feelings of sadness and inner turmoil.

Times are SO hard nowadays. Negativity everywhere...you know what I mean?
Calling your doctor, and making an appointment would be a decent start. The medications aren't working on making life look a little better right now. Are there any resources in the metro area that would be able to help? Salvation Army can be terrific. Hopefully, your doctor can be much more specific on what resources are available in your area.
I hope that things improve for you very, very soon. You are in my thoughts!
