Maybe you could just ask your daughter if she has any questions about therapy. You don't have to go into detail. But you could tell her that you want to function better in day to day life and that you find a neutral party helpful.

It may be best to be upfront with your therapist about the 'turn on' you experience when speaking with her. One really good thing about therapy is that you can learn a lot about relationships right there in the relationship that you have with the therapist. I am sure she won't be surprised - they have heard everything.
