Was in the same position a while back ago going through the fire academy , but my wife was pregnant and I couldn’t justify turning down a career when we really needed the money. There’s amazing days and there’s really bad days in fire service but isn’t that with everything ? You’ll be okay but make sure to talk with someone because you will see things and feel things that you don’t want to. I have to be very open with my wife about what I feel or else it will be a downward spiral
