I know this sounds crazy, but I think my maid is trying to poison me. She prepares food for the entire family, but because of my dietary restrictions, she makes separate meals for me. I have had food poisoning 3 times in the past month and I'm starting to think it's no accident. I can tell she doesn't like me but never thought she was capable of this...my son loves her which is why I'm reluctant to let her go. What should I do?
