Can you just forward her email to your T? I think it is fine if you want another session-- you should do exactly what you feel is best for you, but no matter what, T should see what she is saying to you.

Also, do you want to tell her to stop contacting you, including emailing you? If so, send her back an email stating something like "I do not wish to have any further communications with you. Do not email me. Do not call me. Do not write or fax or text or facebook post or in any other way contact me. If you contact me again, I will report your harassment to the police and seek a restraining order against you."
