My first piece of advice is that you learn the rules of written English:
- Start every sentence with a capital letter.
- End every sentence with a single, appropriate punctuation mark.
- Always capitalise the word "I".
- Do not use chatlist/textspeak. There is no such word as "plz".
We do not write letters for people. Concentrate on those rules of English and then try to write the letter yourself. Post it here and we will look at it.
