My md has recommended that i work from home during the pandemic due to lupus &my medical history. how do i mentally deal with those few individuals who dont understand because i look healthy, am not elderly but have no idea what ive been through?

Ignore them: Follow your doctor's advice for your health. There will always be people who will have critical opinions, no matter what you do. Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs.
