when i am unhappy i will talk to my friend & tell him/her for the reason of unhappy.may be he/she solve the problem.

When i feel happy,I will do some meaningful things，such as study or work.

But when i feel unhappy,maybe i will cry for a while,because i think the tear is good for the person's health, or i will call my friend for my sadness,or i will watch TV to forget the bad things,hah

My friend told me,whether you are happy or not,the life is going on,so I think i will try my best to feel happy everyday.

When I am unhappy, I prefer to be alone. If I am unhappy because I am mad at someone then I find that having a nap gets rid of any anger I had so I do not wind up fighting with the person.

When I am happy, I like to a lot of different things or just be around people. 

Stay alone and go over the whole thing to sort it out when something bad happens;Its like every day is a good day,let the boring and the annoying eat themselves(Ignore or contempt them)

when i feel unhappy i sleep too much more than usually

and when i feel happy i look like children wanna run, play , laugh on anything , see the world look like heaven ^_^
