I know when you had to change providers you had to find someone as fast as possible. Are you feeling well enough to call around and get on some waiting lists and see if you can find someone you get along with better? Tell her you just aren't comfortable tapering lamictal and try to hang in there with her until you can see someone else. Even if you have to wait quite a while you might eventually wind up with someone who listens, which I think is necessary to treat us.
