I am so sorry you are going through this. I will cover you and your friend in my prayers.
Turn you wifi off. 3 days no wifi. At least while you sleep at night. You can steep 1 part peroxide 3 parts distilled water for the congestion to keep bacteria at bay.
Increase your omega 3, 6 and 9. 6 is pro inflammatory then 3 comes behind as an anti inflammatory sloughing off the mucus that has trapped any toxins.
I like LeBlue water and put a pinch of pink, Himalayan salt under your tongue or in your water. This will help drive water into your cells and then potassium flushes the toxins out of your cells so eat some banana's.
I use sweet sooth to settle my stomach. If you can not find it I can send you some if you like. A drop in the belly button or buy some GTS kombucha (no carbonation) but fermentation is good and good bacteria to help settle the stomach. I recommend GTS Gingerberry. Ginger helps to settle the stomach also. This and water can be found at Food L
