jackson has some good points. try to be happy or at least think of happy things. when i feel sad i go outside and just watch the sky (if i can) or i talk to my friends about funny things. it feels great when i watch the sunset because i realize that there's a lot more to life than "human stuff" like girls or tv or video games or homework. and it's just peaceful and cool to watch
i also think about how thankful i am for the family i have, the friends i've made and the life i've been living so far.
