Dear moonbeam,
Try not to be so hard on yourself. Living with depression is very hard. It is like living with any other disease. There are good days and bad days. Depression sucks energy out of you - where does it even go? Who knows. But I know the feeling you speak of exactly. My mind is telling me what I should get done but my body can't move. Take a deep breath.
Sometimes a small cup of coffee or strong black tea helps me for a little energy. Maybe wash 1 cup or 1 dish or pull 1 weed. But don't beat yourself up!
You are important. You are SO much (infinitely) more important than the house or the yard. Why not take a cup of something and just sit outside since it is a nice day?
Sending supportive thoughts your way.
