Jenn, good job just keeping at it.
Some things that have really helped me with my family are that, one, I don't really discuss the diet. I just make the food and put it in front of them. They have no idea if it is primal or not. Two, I keep lots of the things they really love on hand. Each of my family members (besides me) has been going through a carton of blueberries every other day this last week. We have a large sack of chocolate chips (just dark, insteadof semi-sweet) in the freezer. We do dairy, so I always have a variety of cheeses for them to snack on. Three, I serve any non-primal things I haven't weaned them off of, on the side, instead of integrated, and I only make half as much.
For myself, I think I cannot repeat often enough, getting enough sleep EVERY night has worked wonders.
Good luck with your doctor! Don't worry if she thinks you're crazy for thinking diet can impact your mood. How you'll be feeling will be the best proof you're not.
