把中文翻译成英文 谢了啊

请不要微笑,如果你不是真的快乐.
You don't have to wear a smile when sad.

看着你的强言欢笑,我会心痛.
Cause seeing your putting on an air of cheerfulness,is like a knife piercing my heart.

If you don"t happy please not smile
when I look at you smile ,I will hurt

If you don't feel happy truely,please don't smile
When I see your smile reluctantly ,I feel hurt in heart

if you are not really happy, please don't smile
my heart aches when i watch your forced smile
