why the hell do I keep throwing away my time

i woke up at 9 today, didn't eat breakfast until 12, and then wasted 6 hours being distracted by another stupid useless topic. Now I have less than 2 hours of my day left before I go to sleep for school tomorrow. I literally wasted my entire weekend like this and I've still got so much work to do. This happens every weekend. I always forget not to do this. I hate this so much

Edit: yes, I've tried making a schedule and habit tracker but on weekends I tend to even forget the schedule or my habit tracker. Retaining barely anything is a big part of it too.
