I'm sorry that people don't understand what low energy and other symptoms of depression are all about. I do. I guess it's hard to explain to some, but if people very close to you don't, it's time they get educated. Can you bring any significant person that doesn't with you to your appointment? If it is a boss, and they're judging your performance, maybe a note from a doctor would help. They need not indicate your illness. They can think it's something else. Mono, chronic fatigue syndrome, whatever.

I hope your doctor can perhaps adjust your treatment to bring some energy back. In my experience, that has sometimes meant the addition of an activating medication, sometimes the reduction of a sedating one, sometimes a satisfying break/vacation, and/or a new therapy approach. Maybe also ask if other factors may be contributing, like thyroid, lack of daily light, vitamin deficiency, etc.
