Why is it so hard to find decent food to eat?

im on warfarin, I have checked all the diets online for it but none of them work for me. I have blood tests every few days or once a week and they are always all over the place, because of the food. the list of foods you cant eat gets longer and longer every day as you find something else that is not compatible with wayfarin I get so bored trying to find suitable food to eat and variety. you cant eat out no one supplies the food you can have. its so frustrating as the list of foods you cant heve gets longer and there is nothing left to choose from. The big nos are all green veggies,avocado, oils, all herbs,spices, sauces, dressings, gravies, baked beans, kidney beans, mango, berries, banana, parsley chives, pasta, pastry, most dairy, most meats, most fish, corn, carrots, chick peas, noodles, apples, citrus, bread, spreads, nuts, eggs, cabbage, lettuce. cuber,tomato, stuffing, lots of foods make me feel sick. its depressing to have all the foods taken away from you. I do not cook as its too hard when you cant cook what you like. maybe some people on warfarin have no problems but I do with all food I eat, and its so annoying. I am longing for a lovely meal but I cant have one.
