Okay, so it's really stressful being in senior highschool. I know that. Trust me. And I'm not going to suggest that you stop stressing. That's impossible. But I will suggest that you stop for one tiny moment in mid-study and think about how blessed you are. Just by having an education, you are better off than a large portion of the world. Even the small things; smiling, laughing with friends, are worth being grateful for. Focus on these moments. That's what will help you through the stress.
