Its a shame that your mother doesn't really hear what you are saying. I've had less of a problem with this with my parents in recent years, but it still does pop up from time to time (for instance, I don't often tell them when I'm feeling miserable because I'm afraid they'll think I'm whining). Just keep in there with her, eventually she'll come around; sometimes its really hard for parents to see you as an adult who can make thier own decisions rather than as a 12 year old kid.
