So do u think that is the right way that we are doing?

This is a stage for teenagers to be rebellious. The best way is to sit her down and talk. Even when she is starting to pick a fight, keep you cool. Because she is thinking that you are trying to ruin her life when you really are just worried about her. I think searching the room was a little too far but a good way to do this, is maybe not having her stay out so late or have her call you if it is past 11 or you call her just to check up on her. This is just a phase. We were all teenagers once. ^^
