Narrative:

Boarding completed; agent ready to close door; I announced over the PA 'flight attendant ready cabin for door closure;' went and armed R1. I was just getting ready to close L1; and it occurred to me that I had not been catered yet. I ran over to disarm R1. I was able to remove the girt bar from the floor; but as I was trying to secure the girt bar into the door; the caterer opened the door. He did not knock and the red strap was across the window. I yelled through the cracked door for the caterer to stop as the door was not disarmed yet and I needed to finish securing the girt bar to the door. My right wrist and forearm were injured as I was trying to secure while he was opening the door. The caterer was moving in 'hyper mode' way too quickly. We mentioned to him to slow down a bit. A quick note; just prior to this boarding; en route to ZZZ we were experiencing a scary medical and were all still shaken from the experience. My nerves did not settle down until 1/2 way to ZZZ. Please note that the slide never deployed; but I was never able to properly secure the girt bar prior to R1 being opened.
