‘一切都变了、变得如此陌生’该怎么翻译成英文啊?

在不变的过程中一切都变了
All has changed in an unchanging process.

当我再次来到这个地方,天还是那么蓝,宛如记忆中那清澈透明的色彩,这里的一切都不曾改变,五年了,这是我来到这个学校的第五年了.真的,什么都没有变么?
改变的只有我们,我们在这流淌的时光中一去不复返了,是啊,我们再也无法回到从前,童年即将离我而去,只有改变自我.
写了个开头,自己接着写吧,加油,相信你会写好的

since Helen came to our class everything has been change

时过境迁、斗转星移、天壤之别、今非昔比、沧海桑田

Everything here has changed a lot than before.

“追往事，叹今吾，春风不染白髭须。” 上二句今昔对照 ，一“追 ”一“叹”，包含多少岁月，多少挫折 ；又灵活地从上片的忆旧引出下片的叙今。第三句申明“叹今吾”的主要内容。草木经春风的吹拂能重新变绿 ，人的须发在春风中却不能由白变黑。感叹青春不再，韶华易逝的可惜，这是一层；白髭须和上片的壮岁对照，和句中的春风对照，又各为一层；不甘心年老，言外有壮志未能彻底湮灭之意，又自为一层。一句中有多层含意，感慨极为深沉 。

actually,everything has been changed.

Everything has changed so far.

I am here,where it was almost dark
The weather here is cool where I do
I am here,everything changed I became wiser
I started the journal in a while you do
Bright days here,where it soon
I do here,where the weather is very hot
Everything changed me made me cry
I have put away the pictures and that you do
If we now with what will be
Are we still in love with each other
Even as the beginning of daybreak as shaking hands
We now also with what will be
We are not tried to hide each other
As did the end of
You know that you do not forgive the wrong I still insist on
I will not forgive me how to forgive
