The only thing I feel I can offer besides hugs is a trick I learned about fruit flies. For any fruits or vegetables that you intend to leave out on the counter, as soon as you get them home from the store, wash them with soap and water. This washes off the fruit fly eggs so they can't hatch on your bananas.

It's one thing. And these days I know I can only focus on improving one thing at a time.

Hope you feel better soon.
