It does sound very traumatic, even the way you describe it. However, not all people who go through a trauma end up with PTSD. That said, some of the symptoms of PTSD are numbing and avoidance. Disconnecting from your emotions is a version of that. But there are other symptoms that you haven't mentioned so it doesn't seem very easy to say one way or the other. Besides this should be done by a professional. And if it has been already, then talking to the person who has the information about the diagnosis would be what I would do if I had doubts or questions.
