First Therapy Session

So, I had my first therapy session today. I told myself I wouldn't cry. I cried. I ugly cried. I made notes and thought I would be straight to the point like presenting a powerpoint (don't know why I thought that would actually happen). Instead, I jumped right into the heavy stuff, the childhood issues, the traumatic upbringing. I thought that I would start with the things on the surface, but I didn't. Is this normal for a first timer? My therapist was very understanding and patient, saying that crying is a normal response. I've just spent my whole life holding up a shield and letting no one see me cry. I just balled to a complete stranger.
