Does anyone have this, and I mean to the point of always being tired and exhausted?

I've always had a problem with fatigue, and I was told I have a touch of Mediterranean's anemia since I was in my 20's. But now I'm 60 and I'm always exhausted. I'm listless, and I just have no energy at all. This is making my depression and anxiety worse.

What I'm asking is if this can be the cause of all this fatigue, or should I be pushing the Doc's to look for something else?
