The reasons that most folks go to medical school may be unrelated to what it is like to actually treat patients. There is a lot of mucus. There is a lot of actual pain.
And you are more than ever a small fish in a big pond.
Many medical professionals are truly messed-up people who end up hating their patients' guts. They have higher expectations for their patients than they have for themselves.
Go read nurses' and doctors' blogs. They are bitter, angry, dissillusioned people up to their eyeballs in debt. They are people complaining bitterly about the self-absorption of their patients, while posting photgraphs of their scars, surgeries, children, "art", weight loss goals, etc. They claim knowledge in areas in which they are ignorant. Just because they are doctors, they feel they are experts in law, politics, etc.
Amazing to suddenly be brought up short, to discover they are fallible, and that taking care of people requires compassion, and you sometimes lose, and gosh, you are just as human and ordinary and fallible as anyone, and even though you are the pinnacle of human life, you still take off your pants to poop.
