Shadow behind the light

Everyone seem want to outstanding in the light,
Artist show their very best in the shining light,
Student show with the result,
Worker show with their performance,

But somehow every light has its shadow,
The shadow that might no one know about,
The sorrow face hiding behind the cheerful smile,

How about the shadow behind me?
Am i look happy?
Am i stratifies?
The answer might be no,
Maybe im too pressure myself,
Until felt cant breath,
Im too stubborn..
