I would return the juicer to the store. And red meat provides iron pretty much like nothing else (oysters provide more, but... you get the point - among common foods, red meat provides most iron and iron in red meat is bioavailable, unlike iron is leafy greens etc). So if you have a lack of energy, which, among many other factors, can be caused by iron deficiency type of anemia, then avoiding red meat is counter-indicated for you.

What you need to do is make a list of foods that you ENJOY. From that list, choose the foods or food combinations that provide your body with lasting energy. Then, see which of those foods/meals you would enjoy eating at breakfast time. And tackle breakfast, as the most important meal of your day, first. Do not plan to do a complete overhaul of the diet - not only it the task daunting (so you are likely to fail and feel bad about yourself and then more depressed, defeating the purpose of this undertaking), but most likely it is unnecessary.

So focus on eating a good healthy breakfast first, and come up with several doable options so that you can rotate through them to get variety.

E.g. steel cut oatmeal with some maple syrup and a whole fruit each morning, varying the fruit, would do the trick. If you feel better after eating protein, alternate omelettes and steel cut oats as your breakfast choices. Oatmeal can be eaten with dried berries, dried fruit, a bit of applesauce. You can have an omelette on Tue and sunny side up eggs on Thu, and you finely can chop chives to sprinkle on your eggs, for extra vitamins and aesthetic appeal.

Moving from processed breakfast cereals and even quick oats (also highly processed) to steel cut oats is a huge step in the right direction. So I would start there, literally from the beginning (breakfast being the beginning of the day).
