I wish I had a good answer for you...I'm fighting the same thing myself. I just "push through" and try to stay active...I take multi-vitamins, and also take Vitamin B12, as well as Vitamin C. It is indeed a fight, but I do the best I can.

I found this list of the best products to help fight fatigue by doing a Google search:

Vitamin B12. If you search for “how to prevent fatigue” in a textbook or on the internet, vitamin B12 will generally be the number one result. ...
Vitamin C. This is another vitamin supplement that's commonly taken by a large number of individuals. ...
Magnesium. ...
Folic Acid. ...
Caffeine.

Lots of Vitamin D too, but mostly just treat yourself well. Try to suck down the caffeine and B vitamins in a pleasant spot like the forest, near water, or on a comfy sofa.

Hi just want to say that you are not alone with this thing and it is kinda hard not to be depressed. Darn it all. I'm struggling with mds since 2015 and just the past few months I have had bouts of feeling almost normal. Then darn it all I'm back to fatigue town and it sucks so I am joining the group to have some people who understand. My heart goes out to you my friend take care rest and relax and do wherever you enjoy. Blessings to you. Take care

And No One can say how exhausted you should be. Listen to your own body and let what people say you should feel roll off of you like water off a duck's back. It's ok to feel how you do!
