Emotions

Here is a simple equation: new place = new emotions or a New Year new grade = new emotions. Many people feel anxious, scared, or excited about school. Although people who are coming back as seniors may be happy they are in their final year and cannot wait to visit with friends, most freshmen or new kids are likely to be tense or worried.
It is perfectly normal to feel nervous on the first day of school. Getting back to the school routine the energy to get through the day. Foods that have many simple carbohydrates, like sugary snacks, donuts, or French fries may give you a quick rush of energy but it's not sustainable — which means you'll be left wanting more soon after you eat. The same is true of drinks filled with caffeine or sugar. You do not have to cut these out entirely — just enjoy them in moderation.
Stop for a snack. You cannot concentrate or absorb new knowledge without a well-fed mind and body. So take along a healthy snack, like carrot sticks or trail mix, to stave off hunger between classes (don't munch during class, though, unless the teacher says its ok) Not only will this keep you going, it will also help you avoid overeating when mealtime finally arrives
