Im embarrassed lol

My son got his shots today and i went alone so i had to stay in the room this time.. Anyways as the nurse was giving his first shot he started crying so hard, i felt so bad but whenever i get nervous or dont know what to do i start laughing hysterically so of course my weird self started laughing as the nurse was still giving shots and my son was hysterically crying. The nurse looked at me and asked if i was okay and through laughter i managed to say "i dont know" lol im sure she thinks im a psycho
