I pray your friend finds something of value from that channel. The medical world is eugenics masquerading as health care. We have to take our health into our own hands. Maybe that rude doctor was the rude awakening you and friend needed. That isn't to say you won't find a good doctor, but maybe try functional medicine or integrated medicine. First know anatomy/physiology so you know who to look for to help you. Like a team. You + doctor. Some doctors are awesome on the get go but gosh, that is hard to find! God bless you and those who love you.
