Am I overreacting?

Hi everyone! I’m in the background check section of the process and I’m so anxious. I and everyone around me thinks I’ll be a great dispatcher because I’m very good at communication and calming people down. But, I think my downfall is I’m too empathetic? I’m so scared that I’m going to get scared on calls and freeze up or I’ll get too emotional if something is getting dark and I don’t want to ruin anyone’s life because I’m too sensitive. Should I even be a dispatcher if that’s a possibility?
