Try to study more for your next test, or practice really hard at what you want to do, even ask the person for help. There really is no place for jealousy on a cheer squad. It is the fastest way to crumble the unity and bond of a squad. Exhaustion can lead to extreme frustration. But being tired doesn't mean you have to take it out on others.
Cheerleaders know how to juggle their schedules better than anyone during school.
There are always games and practices, but we also have school, fund raising, community work, gymnastics or dance classes, family and other extra-curricular activities. Some cheerleaders even hold down a part-time job. Make a list of your priorities and stick to it. If you need a break from cheerleading or other activities, take one. If school and homework suffer because of lack of time, be sure to speak up.
