How to word termination letter due to my own health

[5 Little Monkeys]

Sorry to hear you're in so much pain!!!

I'd leave the letter short, sweet and to the point. No longer able to take care of a large group due to health reasons, last day will be xxx etc. If they ask or if you want to tell, I'd do that face to face.

As for passing on names of people NOT to contact....I have done that with one provider. The stories parents told me about her were enough for me to do that as I normally mind my own business and don't care how others run their business. She is now shut down due to a pretty serious allegation. I would feel terrible if someone I knew/interviewed had gone to her knowing what I knew.
