I agree with Fancy Girl and am picking up that you need to take as much rest as you can find time for right now. I believe empaths tend to get sick more than less sensitive people.
IME, when you take kids who get the flu and add low resistance to illness due to being bombarded with responsibilities and not enough rest, the result is often Chronic Fatigue Syndrome, not the mild illness it's name implies, but usually a life-long horror show. So, please go easy on yourself.
You have many blessings in jobs that you love. I would hate to see you lose them to chronic illness.
Wishing you health and resilience, from someone who lost it,
