I would talk to the new NP about the situation and how you feel like you want to start over and that you are "worried" what the old NP's notes might say, etc. It sounds to me like this new NP isn't going to just read anything and believe it, wholesale? But it might be good for her to have what was tried for meds, what worked and what didn't, etc. so she doesn't have to waste time suggesting things that might not work or guessing at what could be done "differently"?
