I suggest the same way I’m surviving: one day at a time, like Dog said. Wake up, get to class a little early, eat, finish what you consider to be a solid amount of homework, and relax. Definitely look ahead and know when you need to get started on projects and the like, but don’t worry about what lies tomorrow. You can consider and plan, but don’t dwell on the next 9 weeks or even the rest of this week. Focus on today. Right now.
I don’t know if you’re a religious person or not, but everyone from a Christian to an atheist can’t deny Jesus’ simple logic: “Who of you by worrying can add a single hour to their life?...Therefore do not worry about tomorrow, for tomorrow will worry about itself. Each day has enough trouble of its own.” -Matthew 6:27,34.
