Your doc is right about Latuda being expensive (no generic). However, there is a generic for Lamictal. It was the first medication I was ever on and had no issues insurance wise. Do wait to start Seroquel until you have a day off. I remember it making me tired at first. Seroquel can cause weight gain, so watch what you eat if that is an issue. I stopped taking it because of the weight gain, but it did help.
