My sister went into nursing and thought she would have a gard time with losing patients, but it is a profession where that's what you see often so you learn to see death and dying as a part of living and also its important to realize that as a nurse in that situation you learn that while your patient (the family's mother/father etc) is dying that you are also there to help making the patient's a time of dignified transition while caring also for the family who are present. My sister is a nurse who is exceedingly good at this aspect of her profession and I always will say that I'm very proud of my sister.
If you happen to want chat about your options then DM me.. I'm not nit an expert but I'm a good "sounding board"
