Honestly, probably take some time with yourself first to reflect on your own about what kind of help you'd want to access - if you want a tranquilizer ('antipsychotic'), or an anxiety med that you can take irregularly / non-daily, and know also that there are people like the Hearing Voices Network who focus on working to make-peace-with voices and visions and not treat them as 'symptoms' per se.
Tell her whatever you think will get you what you need, don't let her corral you into anything you don't want, it's your mind and body.
