Firstly you need to be calm. Panicking won't do you any good. Based on your symptoms the disease is not very severe on your case and should be self resolving. You can keep a check on your vitals like oxygen saturation and pulse using a pulse oximeter, regular temperature and blood pressure monitoring. You can start on multivitamins, antiseptic gargles and steam inhalation
