Firstly, I hope she feels better very soon. Hugs to her and you.
Did she help with any gardening? Raking? Dealing with any mildew or moldy leaves, earth, etc.?
My DH did the clearing up of the dead/dying vegetation and got a mold exposure and the symptoms you describe are what he gets every time. I did a lot of rounds of EFT for him, including surrogately, using these phrases:
Even though I have this illness, Iím a great husband and a good man.
Even though I have a fever of 103.4, my body is strong and resilient.
Even though I have this virus, my body can fight back.
Even though I am sick, my immune system is strong, I want it to strengthen, I want my white blood cells to increase to fight this illness.
Even though I feel rotten and have no energy, my body is amazing and can beat this illness!
Of course, you tailor it to fit your child. It is amazing how much this realigns the body systems and aids it to heal quickly.
