ah. well, that's very different from the depression I had, so not much *I* can suggest, unfortunately.
It might help, if you tried to identify whether your "lack of energy" is due to your feelings, or your body directly. It's tough, since lack of physical energy strongly influences mental energy, after all. but if, for example, you (or a helpful doctor) identified it as physical, then you might be able to do some kind of physical therapy, or possibly medication/suppliments, to help you with that.
