Tenant mentally altered?

[Laura7797]

I think my tenant may be mentally altered.  I have an elderly lady and she is reaching out to me multiple times daily for help with things that are very simple and have already been explained.  This last message says she is scared to poo because she thinks the toilet may not flush.  I've checked it and it's fine.  I want to be kind, but I she burst into tears over my showing her for the third time how to use an electric kettle.

Sigh...what are my obligations here?

OK...now she says she can't poo because she thinks the toilet will explode.  She's wandering around in the yard near my porch talking to herself.
