That is a great point, Insights. The doctors/therapists really do listen to what you tell them. And tell them everything, because things that you think aren't relevant, actually might be relevant.
Sometimes a first appointment can be frustrating because the therapist has to ask a ton of background questions and you might feel that you just want to solve your problem. But I think the fact that your first appointment is two hours is good, hopefully you will be able to do both!
