I don't have anything insightful to say. I loved Migzillion's wish that you'll find something that will fire you through inertia, or a series of somethings. Hang in there. Clearly you know how to do that and are doing so. Just didn't want to read and pass by without sending you a virtual hug of some sort and hoping for you that the depression goes back whence it came. I can personally empathise from my own experience. I think you'll find strategies that can turn it around.
