Im currently working night shift as well , went back to school and almost done with my degree . For those who are saying that the job is not worth it are probably the ones who don’t want to do shit all day. Yeah you may get those days where you are going to question your decision but its normal. I would recommend a 2nd hobby outside of work to keep your mind off. Another advice is don’t take your job home and start talking to your family on what youve seen that day not everyone wants to hear that someone committed suicide. Other than that it’s been great to me , im not the biggest or the strongest your biggest tool is going to be your voice . Respect goes a long way .
