Not sure what I have

Stop worrying about what she is thinking.

I would suggest not answering her email right away. Maybe meet her somewhere other than the house, say you will be out and about and not at the house. She can't get in the house can she? Leave the health issues alone and keep them in your mind, but don't say anything that lets you know you've been looking into it (that would be pursuing IMO). At this point you won't see anything showing she cares. Good luck!
