My own experience had sent me in a downward spiral. I had no idea what was wrong with me, no energy, lethargic, and off my food. At the same time I had a family of 4 children at home to support as an only parent.
The thing with fatigue is you don't look sick on the outside. Family, friends, work colleges often don't understand "I am not lying down because I enjoy it, I am lying down because I barely have the energy to move."
I had been to Doctors, health practitioners, and was just not getting anywhere. The lack of energy was annoying, the lack of not knowing what was really wrong just as frustrating. I even felt like I was dying for a period, and I was unable to work effectively so my finances were in a disastrous state. I just wanted to curl up in a corner and hope life would sort this out for me which of course isn't how it works.
Public health funding only covers medical services so this was a very difficult circumstance.
