That's a LOT of fat in your diet. No wonder you are feeling so tired and dizzy. Because of biochemical individuality, we are not all the same and therefore shouldn't follow the EXACT same diet. But I am willing to bet that the excess fat in your diet is causing plenty of problems, namely simply being too much fat and all of the fat taking the place of more vitamin/mineral rich foods. Try getting more carbs, quinoa and sweet fruits like bananas and mangoes are some good options. If you eat enough calories to support your body, you are more than likely getting more than enough protein. The huge concern over protein just shows how uninformed people are.
Seeing as you already get so much fat, I would not recommend adding more fat in the form of peanut butter. That would just increase your omega 6 fat intake as well. Try some lentils or other legumes (sprouted or cooked). They'll increase your protein and carb intake. Also, just because you eat more fruit than veggies does not mean you are automatically deficient in anything. It's all about how much total fruit and veg you eat. I eat about 1.5-3 pounds in just green leafy veggies daily (in addition to other veggies), but I eat more fruit than that to get adequate calories. So I'd suggest try doing some more green leafy veggies for minerals and vitamins. You could do a smoothie with some bananas and kale or spinach. After eating more mineral rich foods and less fat, if you're still having issues, go to the doctor. You are an adult, your health is important. There's simply no excuse for not being physically able to get to the doctor.
I've done a lot of research on diet and health, and I personally believe that you would be doing more harm than good for your health, and the chicken's, by adding animal protein to your diet.
