As Tempeboy's link points out, fatigue can have many causes, not the least being that our bodies are now constantly dealing with an invader.
My numbers and health are good it is just between my ears, aka in my head, that these feelings are coming from.
That is spot-on, Jeff. All feelings begin with a thought. Change how you’re thinking and you can influence what you feel. It's not always easy to take charge of thoughts, but it can be done.
