Aww sweet, as the others have said, you did the right thing!
The best thing to do in those situations is put bub somewhere safe and leave the room for a few minutes, calm yourself down and try again.
I have so been there, many times and once I even yelled at DS to just shut up... that's when I knew that I had to walk away from the situation for a couple of minutes, and boy did I feel like the worst mother in the world, this poor little bubba that obviously isn't happy about something and I yell at him? But a couple of minutes just sitting on your own will do the world of good for you and Jazz, so please don't feel bad!!
