“I believe I am vulnerable to COVID-19?”

I have been receiving disability benefits since 1996 for several different conditions including Guillen Barre Syndrome. In late January of this year, I had two grand mal seizures and was taken to the hospital after the paramedics revived me back to life. While hospitalized, I was diagnosed with double pneumonia and referred to a pulmonary surgeon who explained that I needed surgery to drain the excessive infected fluid. During the operation on February 3rd, they also removed my left lung. So, my question is; If I contract this coronavirus, are there any medications or treatments that would lessen the severity of this disease. I am really scared, confused, and frustrated over this.
