Well... I'm tired all of the time too.

But I'm old.

So it's to be expected, I guess.

On the other hand, fatigue is something I think I've always battled.

I've struggled with depression as well. But I think the high levels of anxiety I've always endured was, perhaps, even more wearing for me.
Here are links to some articles, from Psych Central's archives, on the subject of how to cope with depression & fatigue. Hopefully some of the ideas in these articles can be of some help:
