Welcome to the forum, NirmalaCulli.
I asssume that you want us to check this letter and make corrections if necessary. It would be helpful if you made that clear.
I am not very good at proof-reading/correction, so I will leave that for others. I'll just say that you need to leave a space after a punctuation mark, and begin every sentence, and people's names, with a capital letter. I have underlined the three places where you need to check this.
