Maybe your parents are a bit possessive of you?

I don't have children and I never want any but if there is one thing I can speak of from experience is that I've done stuff like this in the past for people that I am possessive of myself such as close friends by lashing out and threatening people who I think hurt them in any way without knowing the whole story.

I guess all I can say is if this bothers you that much (I don't understand how it does considering that I would kill for somebody to care about me that much to do stuff like this) to get away from her.
