Okay, well i have read many stories of girls (or guys I guess) who are physically abused by a parent. But is there a such thing as Verbal abuse? My dad kind of puts me down constantly (like your a sl*t, and things like that), and I want to know if its a serious issue and if I should tell someone, or if it isnt anything to worry about.
I suggest that you tell your dad you don't like it when he talks to you like that and ask him to stop. You never know it might work.

Have you ever told your dad how his put-downs make you feel? If he is not aware you should seriously speak to him and make your thoughts and emotions known. Is speaking to your mother about it an option? You never know what may work.
But if that fails, I do not know what you can do after that. Honestly, I don't think CPS can help.
