Am I happy?

Am I happy? --Oh! I'm very happy.
I have a computer at home, I have a TV, I have a radio, I have a snack, and I have a big bed to sleep. Fortunately, my aunt and I are good to me. I often send things to me. My cousin is close to me and has difficulty studying her. I will help me; my aunt is very funny. I like to say some funny things about my cousin. I laugh at my stomach. Sometimes, my cousin and I still laugh on the ground. Every time I go home from school, my grandmother is ready for me. Dim Sum; every New Year, Grandpa and Grandma give me a lot of "tickets"; although my grandmother is going to take care of her grandfather every day, when I come to her house, she will also go home from the hospital and open the door for me... Everything makes me feel very happy.
Sometimes, I feel very unhappy.
Although there is nothing in material matter, there is a big basket of troubles in learning. Mom often said to me, this is not good enough. When the English test papers are issued, both parents will open a "lecture" together. Of course, I am a person who listens to the "lecture" and sat and listened for more than an hour. Although I don't have to pay for the tickets, the whole hour of smashing will make me dizzy, backache, backache, weakness, bones, and sleep.
I am afraid of the exam, and I am even more afraid that my parents will open a "lecture" after the exam, which makes me very unhappy.
Happiness and unhappiness, which one is more? I'm not so sure either.
