Makes me thankful I'm going in already knowing medicine is basically a **** show. I feel like a lot of those letters are just reflections of idealism that's been dashed against the rocks of reality and bureaucracy. It's sad, because medicine should be an idealistic profession, but with the way things are structured these days, there's little room for idealism or creativity, and it's probably only going to get worse as time moves on.
To anyone that might be lurking this thread that is depressed or considering suicide, try to seek professional counseling as soon as possible. Stress, sleep deprivation, and being torn away from friends and family can easily get to even the best of us over a long enough timespan. Medicine may be a calling, but at the end of the day, it's just a career. Yeah, on its best days, it is a magical one that gives you the warm fuzzies after a good call or a successful resuscitation, but it's still just a career nonetheless, with a lot of flaws and blemishes to go along with the nice bits. Military aside, no career is worth sacrificing your life or happiness for.
