中文翻译成英文，你可以吗？

There was a sincere love in front of me, I do not cherish, such as lost time when I regret that the human world of the most painful thing is this. If God can give me a chance to once again, I will not say: I love you! If I were to add a period of three words, I hope that is 10,000 years!
曾经有一份真挚的爱情放在我面前，我没有珍惜，等失去的时候我才后悔莫及，人世间最痛苦的事莫过于此。如果上天能够给我一个再来一次的机会，我会对你说：我爱你！如果要我给这三个字加上一个期限，我希望是一万年！
