The virus is transmits by aerosol. This means ventilating is the key. Ventilating for hours, be outside as much as possible (fresh air) and keep your immune system high (avoid the stress a lemon won't do the trick).
I doubt you could have avoided it. By now vaccinated people get it and turn into super spreaders.
Own immune is the best, T-cells + immune system works for decades if not your entire life.
I am sorry to hear about your family.
After nearly two years I and my family still know no one who became sick or died from it.
All the best for you. We can only do our best and find a way to live with it just like the flu.
Perhaps it helps you to read the WHO site if it comes to facts!
