Day 13, you are in a time of transition. It will take your body and mind healing time, but I certainly agree with Teach about seeing a Dr.
I do not watch tv or movies for some of the reason you said whenever my anxiety is not treated. But I know the feeling, I have been in college classrooms where a video is shown and my mind just won't stay with it...not even for 5 minutes. But thinking on it, it is not because it is too fast paced, however it does over stimulate me when my anxiety is not treated.
If this is something you have enjoyed in the past I feel fairly sure it will come back to you. Every cell in your body is in a state of shock right now.
