Let her know that you realize that she'll always worry about you and you love her for that. Tell her that she has raised you right and to be a responsible adult. She must trust you on this. Since you are living in her house, though, you should sit down and compromise on some things for now. Don't let her down. I think she'll understand and you should be able to prove to her what a great daughter she has raised. Good luck.
