I know EXACTLY how you feel. The only time I feel moderately happy is at night, which is one reason why I think I stay up so late at night. Sadly, the other reason why I stay up so late is because I put off my homework as much as humanly possible. The only time I feel like doing in work is in school because I have to. Homework is just such a chore for me because I get distracted too easily and because I'm way too lazy lately.
