Ways to battle chronic fatigue?

I had two babies back to back and it took a toll on my body. I am anemic and low on vitamin D. Currently taking prenatals still, an iron tablet, and a vitamin D supplement prescribed by my doctor. What can I do to battle this fatigue in the meantime? I know I don’t eat well enough and I need to drink more water. Those are the obvious ones. But wondering if anyone has additional advice. I can barely get out of bed. I sleep so much. I’m also on an antidepressant that is working wonders so far for my mood but has no impact on my energy levels.
