The day that disturbing calls do not bother you is the day you should get out of EMS; but with that being said, please keep this in mind:
1. We do not cause the pain or ailment, we respond and do our best for each patient, and often, that will not be enough. It's not fair, it's not right, but it is reality. We see, smell, and remember things that no one should, but who would do it if we didn't. You will never find me running into a burning building for any reason, but I am grateful that there are people who do. You have to do what works for you in these situations, whether that be CISD, talking to whomever, but at the end of the day, we do need you back in the saddle. There are a finite number of people who can do this job, and even a much smaller number that can do it well. Should you choose to leave and take on a job that is less stessfull, who will fill that vaccuum? Yes there are plenty of rookies in the pipeline, but which of them could jump on the truck tomorrow and be as good as you are after 8 years?
2. For every one of these "bad" calls, remember the many good calls where "you" touched a life, even if you did not save it. I imagine there are several folks walking this earth today solely because you were there in their moment of need.
3. The following is probably the dumbest/corniest advice you will ever recieve, but it is applicable in many ways:
