I want to eat more raw fruits and veggies

The world doesn't make any sense to me. I consider myself a healthy person. But these last few days I have been lethargic, constipated, tired, and dizzy. My skin is oily and gross and I have acne. I get headaches. It seems like my belly is bigger than normal.
This makes me want to be more extreme with my diet. I want to just TRY raw veganism loosely for maybe a few weeks to see how it works on me. But the problem is, I live in a household that would probably make that impossible. My parents would say I don't need to because I'm "already healthy." They say raw vegans are "weird people" who "get ideas into their heads." I want to buy large amounts of fruits and vegetables like FullyRawKristina and other raw vegans do, but my parents would get really mad at me for purchasing so much. They are the type of people who don't buy anything until they run out. Once, I bought some raw milk because I was going to run out by the time I go to the grocery store again. My dad got made because "I already had some" and "I'm the only one who ever drinks it anyway." This is not to mention he HATES raw milk. I want to eat more raw fruits and vegetables, but on one hand my family would get mad that I ate all of what we had in the house, and on the other they would get mad if I bought "too much."
Meanwhile, my mother is prohibiting me from purchasing any greens. This is because we are going to be harvesting bok choy and kale soon. I love spinach and a lot of my recipes call for it, but I'm not allowed to buy any.
