It is so important to remember that This is about you, not about your therapist. Like other posters have said, if she is well trained, this is something she is equipped to handle. If it changes things, then she has made it about HER and her skills may not be very well developed (though from what you've said, this is not the case).

A piece of advice i was given was to preface the conversation by saying "Im telling you because I am having some intense feelings and I think that sharing them with you will help me better manage/deintensify them"

Thinking of you!
