If this is your first time, then the psychologist is probably going to ask you some pretty generic questions. The first and foremost is probably going to be why you are there in the first place. Your best bet there is to just answer as honestly as you can, they will be able to help you the best if you are honest. Are you going because you've been depressed? Agitated? Angry? Problems at home? Feeling overwhelmed? Where you victim to some sort of trauma? Remember, if you were the victim of some sort of trauma, you should tell the psychologist, but if you don't want to talk about it yet, you don't have to. What types of questions you are asked after that will depend on what you are seeing them for in the first place.
