I cannot create a pamphlet or anything, but I can tell you some coping strategies to go into highschool.
Highschool is not as bad as the movies make it sound, so don't turn to them for help. Just be calm, and relax! The night before your first day of school, don't think about it too much, or you can stress yourself out before you even get there. Just set out your things, such as clothes, school supplies, etc, so you're not rushing around in the morning.
Hope this helps!
