Welcome Muffinz! Primal is not a rigid set of rules. You need to find what works for you.
You should give up soy. Corn, oats and white rice are not too bad. Try to use organic, traditionally prepared corn and oats, e.g. old fashioned oats soaked overnight. Traditional corn tortillas. Potatoes are fine if you don't particularly need to lose fat. I eat all those things except oatmeal and do fine.
What do you do for protein? You do need some animal food. At least eggs, and dairy if you tolerate it.
If you switch to ore protein and fat, and less carbs, you will find that you don't need to eat as often. But women may need to eat more often than men. (Millions of years of men hunting and women gathering and nursing.)
