cycle life has changed

My life cycle has changed lately. my activities I do at night and I did my break in the morning. I have been addicted to playing poker until daybreak. If not playing poker I spend time watching movies until midnight. I often do not attend the lectures and makes me not graduating this semester and must restart it in the next semester, thypus disease twice, bathe in the afternoon, and much more detrimental effect my self. I do not know how long it should be like this? hopefully I can change and be better .......
