Torn,
I can understand why this email hurt you, although I do not believe that was it's intention. It sounds as though your T wants to keep trying to help you although she is not sure how and she is asking you to guide her?
I don't like the way she phrased the walking on eggshells comment though, it would have sent me into a spint too as I am very sensitive and have had people say they are walking on eggshells around me but I have since realised people use this as an excuse for their bad behaviour too.
I hope you can forgive your t and work through this as I think she made some mistakes but is willng to work through them with you.
