Dear Jane!
I was very happy to get your letter and now I am writting a letter.
At your letter you described me your problem touching your parents and you.I decided to give you an advice.
If they don't believe you,try to show them that you can be independent.Choose your clothes yourself,cook breakfast and do your homework yourself.They will understand,that you can be independent.
Write me an answer,please.
