I feel your pain.
When the depression is bad, it is hard to find any energy to do anything. I think a slow walk outdoors might help.
I have found when I push myself to get dressed and go for a quick walk in the morning, it really does help elevate my mood all day long. It is about the only thing that I can rely on.
The Japanese have a term "shinrin-yoku" forest bathing (a short blog post explains this
http://wellnessiis.wordpress.com/201...forestbathing/) in which just being in nature (the sounds, smells and sites) is meant to have restorative benefits.
Be well and kind to yourself!
