I was a combat medic in the army for 6 years, and I've worked in assisted living. They're wildly different experiences and required different things of me. Depending on how you want to practice medicine and in what capacity, there are different things that will affect you in different ways. As a combat medic, we see terrible things and they can change a person. For a role such as that, coping can be difficult because they're your comrades. The attachment is built right in. In the medical field, on the civilian side, they usually tell you not to get attached because it can sometimes wreck you if you ever see life or death situations. In assisted living, it confronts your fear of dying in other ways. For me, the family members were the hardest part of that job and I'll never forget being a shoulder to cry on. My point is, you can study until you get perfect scores and you can do your research, but until you're there, you will always have to face something you won't find in books. The emotional tole breaks people all the time. It's not always negative. Sometimes you'll hear a baby's first breath or watch someone learn to walk again. You'll see awful lows in this life, but you'll also see tremendous highs. That's something you need to be prepared for. You'll do so much good in this life.
