Hi Nicholen,
Sorry to hear you're having such a tuff time of it. You have taken on an huge task, but it certainly sounds like you are up to the challenge. GOOD GOING!
Have you been anorexic for awhile (years)? How is your weight (in proportion to your height) right now?
I sure don't want to diagnose here, but your lack of energy COULD stem from the fact that your body simply does not have enough fuel (immediate AND reserve) to to propel you through your day.
Remember, food is the fuel that runs your body, kind of like gas in a car. Also like a car, if you are giving it inferior fuel (which pizza and mac'n'cheese ARE), it is going to ping, chug and sputter.
Energy foods are, generally, the whole plant foods, you know those vegetables and fruits so many of your age detest. Also, GOOD quality proteins.
If you continue to refuse food, or ALLOW yourself to remain a picky eater, your situation is not likely to change. Supplements are ok for some, but they CANNOT replace the benefit of eaing correctly, no matter how many you take.
You sound like a pretty bright young adult. Educate yourself, home ec (cooking class?) teachers SHOULD be able to offer you some pretty sound advice on how to turn this around.
Good luck, and hang in there, you're doing great so far!
