I am very sorry to learn that you are unhappy now. But I don' t think you should be unhappy.
我知道你现在闷闷不乐，感到很难过。不过，我并不认为你应该如此。
I know that your family is not rich. So your parents can' t afford to buy you something of famous brands, which makes you unhappy.
我知道你的家庭并不富裕。所以你父母买不起名牌给你，这使你不高兴。
But they have sent you to school so that you can receive good education and have abright future. This is not easy for your parents.
但他们送你来学校读，让你能接受良好的教育，有一个更好的未来。这对你的父母来说并不容易。
So you should think about your parents. Don't ask for something that is out of your parents' reach. Don' t be vain-glorious.
所以，你应该想想你的父母。不要要求得到超出你父母能力范围的东西，不要爱慕虚荣。
I also think you should put your heart into study. Read more books and then you can get a lot from reading.
我也认为你应该将精力投入到学习中去。读更多的书，然后你可以从中学到很多。
Without the famous brand competition you will become happy. I hope I can help you out of unhappiness. Wish you happy. Yours, Huang Ping
