Several things here followed by a non-PC thing. First the nice thing, maybe she's so protective of you that she feels the need to protect you from harm and make sure everything your doing is good for you. That's a positive, right? Annoying, but positive. Now if u mean she's nagging, constant reminders and double checking in an annoying voice, yikes! Next time she's out and about and you're home/elsewhere, call her and tell her "we need to have a serious talk. what time are you coming home?" Reason I say this is she will totally freak and try to get u to telll her as it sounds major, so she'll pay serious attention. When she gets home, tell her the ways she handles you that u don't like. Explain her ways remind you of your Mother and it's such a *****-killer that it turns you off as there's nothing attractive about f***ing your Mother. She'll stop after u tell her that.
