any thots on therapists keeping notes on the patient?

[ellenrr]

I visited a therapist about 10 times.
each time she took copious notes, which made me uneasy, but I didn't say anything.
I did note that she keeps them in a big, bulging briefcase, presumably with all the other patients notes.
I am no longer going to see her.
I want to ask her to destroy her notes on me.
Of course I can't confirm she will, even if she agrees.

But if she doesn't agree, I'd like to know my options.
seems to me I am within my rights.

thanks
