Can you help me write this in chinese characters?

1) you care now?

你現在關心和在乎了嗎?
(when wrote in traditional chinese - which usually used in taiwan, hongkong, macao...)

你现在关心和在乎了吗?
(when wrote in simplified chinese - which usually used in mainland china, singapore....)

2) stop been lying to yourself!

不要再欺騙你自己了!

不要再欺骗你自己了!

and

"be quiet already! go have a life."

冷靜下來地去過活吧!

冷静下来地去过活吧!

You need to write in better English to allow us to understand what you are trying to say .. and context ..

Are you trying to write a play or something ? It is difficult to just translate one sentence in the middle of emptiness. It will be easier if we can understand the ambience .. and context
