请各位英语高手帮我翻译一下.!thx a lot.!

A two-day time period can change one a lot.
Not only you thought, but also you apperance.
All these makes me feel how scary human beings are.
I once tried to change.
Tried to find a new starting point with you.
But you hoodwinked your eyes.
You concealed yourself in the past forever.
You cannot see my efforts, my tears.
Or I should have realize all these earlier.
Let us end happily.
But another self inside my heart tells me that
I am just too naive.
I thought letting you go
and setting you free are enough for you.
The smile you gave me when you left is like a knife.
It hurt my pride and heart so badly on my back.
It made me unable to face my life.
I know that I cannot forget you till now.
The more I see the happiness between you and him, the more I feel myself in an awkward position.
I show my insincere smiles to people.
As night comes, my mask breaks apart.
My heart is bleeding.
I could make others happy.
Then why do I alway put myself in agonies?
You are right.
Being nice to others is like treating onself with cruelty.
It was me the one who let you go.
To search for your hapiness.
Then where is my happiness?

the time of two days is enough to change a person
inwardly and outwardly
...
...
...
...
so how comes my happiness?
