That is sad. It will lead to nutrient deficiency, which will contribute to depression. So you are in a vicious circle. Can you think of anything you can cook for yourself? One-minute oatmeal for breakfast for starters? If you fill it with different components (chopped dates, berries, nuts, etc., with butter, without butter) it would be less boring than pizza and Chinese, no? What else can you think of - something simple - that you can bear the thought of cooking for yourself?
