Hey,
I hope the session goes well. Try not to be hard on yourself for not talking as much as you would like, it can be very difficult. Perhaps the actually inablity to talk is something you need to ask her help in and see what way you could both work around it (maybe by writing or emailing before a session etc).
I think it's understandable to find the noise distracting, I know I would too.
*hugs*
