I would hate to say you get used to dealing with death and children, but you do. You learn how to cope with your feeling related to it. I have worked ER for the last 7 years and have two young children. In the ER you will laugh and you will cry, it is part of the job and you area person with feelings. Keep in mind you loved er vet medicine. The human ER is much much different than dealing with animals. Keep you options open and explore what to do. You just started school you will have exposure to many different areas.
