I am afraid I will disappoint everybody

I am a student, but I do not manage to study. On highschool everything went super easy and I hardly had to do anything to get high scores. Everybody expected a lot from me when I went to the university, but that makes it only more difficult now.

I make up excuses, postpone work and rather go out with friends or spend the night on the couch gaming then to study. I am scared I disappoint everybody.
