Welcome to the forum.
We don't write letters for people. Please try to write the letter yourself, post it here and we will look at it and see if any corrections are needed. Remember to follow the rules of written English:
- Start every sentence with a capital letter.
- Always capitalise the word "I".
- End every sentence with a single appropriate punctuation mark.
- Always put a space after a full stop, comma, question mark or exclamation mark.
