I feel tired all the time too. This has been the same off and on for the past 2 years, meds or no meds. I think alot has to do with the depression itself. You are not lazy, it is a disease, I mean who would wish this on themselves?? Who would choose to stay in bed instead of being with friends enjoying themselves? I have lost all interest in anything but sleep. Not much help, I know, but at least you know you are not alone
