Advice please: I cannot find the post of a doctor

Advice please: I cannot find the post of a doctor here that gave advice awhile back on what to take at home if you have COVID. So I am barely Asymptomatic today with a slight headache, very mild head congestion and received a positive test that was supposed to just be a precautionary test on Monday..dang it, it got me. I am a little nervous. I am a 44 yr female. I have had a lower lung lobe removed years ago, an autoimmune disease my entire family history is cancer and autoimmune diseases litterally every female had or had breast cancer but me and jacked up mutated genes. What can I do from home to prevent progression and knock this crap out. I have inhalers. I know I need zinc and vitamin D3 don't know dosages to take and whatever else I need. Your help is appreciated! You are all amazing here and I read all your opinions, insights and advice ❤
