just a thought , if you find it difficult to broach this with your T, why not write her a letter about it or print off what you wrote on here and hand it to her. She will have heard of similar before, so it will not be a suprise for her. i find it much easier to hand a letter over, i then try to concentrate on 'wow, i really did it, i really have told her, i really handed her the note' that way i only feel uneasy for a few minutes while she reads it rather than squirming to find the right words and explaining misunderstandings!
