so much stress!!!

I've always been stressful these days and it's the beginning of my university life.Before it,almost every one told me that how colorful it is,or sth like that!But there are so many tasks,,,everyone seems so working hard…scores,scores,scores,,,I'm stressful,I am!I even can't find some one to chat cuz they stay in their own circle…I't not what I expected!HELP ME,I don't know what to do.Maybe its a silly question but I do feel puzzled.
