Is this normal for you, or is it "diet" food? Because it looks to me like you're not getting enough calories.
Your breakfast is probably running about 300 calories. Your lunch is probably under 500 calories, and your supper (depending on quantities) is maybe 800. So you're looking at, probably, under 1600 calories. If you are a nursing student, you are on your feet and working hard all day; you need more calories than average.
This calculator (
http://www.freedieting.com/tools/calorie_calculator.htm) gives you a rough idea of how many calories you need to be consuming based on your height, weight, age and activity level.
I'd bet dollars to doughnuts that you're not eating nearly enough calories for your body type and activity level. If you eat larger meals throughout the day, that should lessen your early morning hunger. (It will also lessen the chance that you slow down your metabolism.)
Also, make sure you are getting adequate amounts of good fat. Full fat dairy, cheese, nuts, and olive or walnut oil are all good ways to get some fat into your diet, and fat keeps you fuller much longer (especially when combined with the fiber you're getting from the fruit and beans).
