Update.. The doctor's office just called me back. It was a nurse who called me and I told her my questions and she's sending them to a doctor. She said that she recommends I go ahead and switch to Lexapro, but also said that if she hears back from the doctor, she'll call me.. If I don't hear something back by 5 (it's 4 now), she thinks it'd be a good idea for me to just pick up the Lexapro from the pharmacy and switch this weekend.
I'm making a separate post in this thread so I can get myself more positive (and less afraid) about switching meds.
