我寫了封英文信給我媽的弟弟,可我英文表達不清楚,能幫忙改改嗎?

I believe "greed" and "mean" was being spat by human even we are from different culture.
When my family came to the United States, We try to pursue equality and justice.
My mother hold herself aloof from the world, but you try to shrunk her benefit even from a piece of heritage.
Your father and you treated my mother as beggar. Is this fair to my mother?
My mother had lost her father's love since her 9 years old, Your father treated his children very big different.
Your father given almost all property to you, only left a piece to my mother. even this "piece" was controlled by you
and share with your children. I believe the United States 's Law can adjust this affair. I also believe this will was driven by you. because you had lived with your father more than 40 years. My mother is so self-discipline.
She was never ask for her travel and medical expense from the "piece". My mother also blocked me to do
any legal action. because my mother believe there something more than money. finally, I want to tell you
If you switch the position, How do you think your father? God really take care of you, But we are going to take
our self.
