You represent the voice of so many teachers who have had to leave their work place or retire early for the same reasons. On the one hand we are seeing a serious shortage in teachers and on the other we are unable to accommodate ones who want to work.
Working through this can’t be easy, but I hope some online avenues open up for you. You are a fab writer and I’m sure an excellent teacher. Perhaps, look into online test prep or essay writing workshops for high school juniors/ seniors. I know parents pay $250 an hour for private tutoring. Just a thought.
