麻烦帮我翻译一下这是什么意思？

you have gone to a place I have never been. I have never heard. Before the time you have to leave, I even don't have time to meet you and say goodbye to you. But you leave a promise between US. This last a long time for more than four years. And it have a long distance. So far away, so sadness.

I wonna say, you are not alone. Cuz you have many friends and there is a person who is holding a fantastic promise.

I wonna tell you. You are the most special girl I have ever met. Everything is so amazing. Not only your promise, but also, many many details. I will hold it. Better than you can imaging. Have a nice life style there, my DEAR. Both of us are very happniess.

I will be waiting for you. I will be BACK. Just like the promise.
