When I was in elementary school, I cried anxiously because I forgot to bring my homework. At that time, I thought it was a huge deal. In college, I failed a course and also felt like the sky was falling. Life was over. But now looking back, it was nothing. Small matters. There are even many things I once thought were huge that I can't remember how I felt about now. If you're in such a difficult situation right now, just take it slow. Eat well, sleep well, and get through this period, and you'll get better.
