This has happened to me before in high school and now it is happening again. When I am under too much stress I just zone out, playing video games and wasting time for 8 hours a day. This was responsible for a serious drop in high school grades. I thought I was over it when I did great in college up until now but now I am doing it again because of my software engineering class. Now, wasting time on watching animations and playing games is harming my performance in all my classes and I can't make myself stop. Anyone have advice on how to stop this?
