Hard day

Last Saturday is very very hard for me,because I woke up at 6 o'clock A.M and played the game of baseball. I came back home at 4 o'clock, so I needed to go parttime job that I couldn't sleep.My part time job is a clerk in the bar. I went to parttime job,but as I was so tired I couldn't work well. I thought I can't　continue this job.
