Dr, please advise several weeks flu symptoms and not well

Priscilla said Dear Doctors, First thank you for all you have done for so many.
I think my question can be answered with your medical expertise. I am in area where Coronavirus is quite bad and recently traveled domestically to visit my family. They were worried about the new virus outbreaks in their area and their city already in state of emergency. The week before my travels I felt as if I was having a dry cough and fatique. I took a few doses of spongia which cleared the cough. But a few days later I had a very low grade fever 100 and so I delayed the trip by plane two days so I could rest and feel better. I also had a scratchy throat and so I took a few Belladonna 30c in divided doses.
I was fine there except my temperature started being around 97. Every day since, both while there and now that I am back home, I experience momentary fatique and almost a lightheaded drunken feeling and when I check my temperature, it is low again. During this time I feel overall like I am getting the flu. My tongue is white coated, a vertical crack in the center, and a few red dots. I have a very mild sore throat and still a dry cough. My eyes also are dry and I sneeze a few times in the day. I am concerned about my immune system with the virus now having reached my area and because of my travels I am isolating to make sure I do not harm anyone. I have felt very sad about the people around the world suffering with this virus. I am Pulsatilla constitution and have taken two doses of 1m in the last week that I believe helped me. I am drinking carbonated beverages. I have studied Bryonia, Gelsemium and others but do not know which remedy will make me feel better to avoid getting worse. Can you kindly advise? I so appreciate your help. Thank you again, and good health and blessings to you all.
