I think what this forum needs is a bit of philosophical perspective.
Literally no med student is prepared for medical school. We get here and think, "M W F for 3 hours." Then I'll study some, party some, and it'll be good. Like College. WRONG.
The first two years of medical school will be the hardest adjustment you will ever make. You realize that its class 8 hrs a day, reading another 8 hours a day, and maybe a day off each week. Its stressful, its long, its exhausting, it isnt fun. Its hard.
But why is it so hard? Its hard because you are entering a world of complexity. The thing that separates a physician from every other health care provider is two fold. First, it is the sheer depth of knowledge you will have. Second, it is understanding why we do things, not just what.
I relate medical school to how you learned language. You first say a few words, and develop vocabulary. Then you learn how to put those words together into sentences, developing vocabulary. By the time you reach third or fourth years you will be writing prose. Beautiful poetry, sonnets, and essays with the slightest of ease. But you must go through the pain staking nonesense of learning vocabulary (year 1), then grammar (year 2), then finally reading and writing. And, just as language is inherently natural to you now, so too will be disease.
Let me relate to you a story. As a paramedic student I had a patient with hepatic failure. My preceptor asked me what we should look for. I was able to regail all the problems of not having a kidney. Oops. That mistake, now, is so far fetched. The difference between the word renal and hepatic is as simple and trivial as the difference between "the" and "is". Now, so too are the things that can go wrong with each organ, the lab values that track them, and the treatment options for both.
The point is that you have to go through the not fun stuff in order to inherently and implicitly understand the end result. Will you recall every nerve or artery you found in anatomy? Of course not. I don't even remember the brachial plexus, and we spent a week on that. Do I remember the different pathological findings of cirrhosis on a needle biopsy? Of course not. But if some one said to me ballooning-degeneration and bridging portal fibrosis I would go "OH! OH! CIRRHOSIS!" Not only do I have the vocabulary, but i have the understanding to recall lost information when prompted, to relate that to pathology, relate that to a potential patient presentation, and then be a doctor.
When some one says something like "ACE-inhibitors are used in congestive heart failure to improve renal perfusion while aldosterons is used to prevent continuing fibrosis," do you know what they mean right now? I mean, you might be able to look up the meaning of the words, but do you implicitly understand why fibrosis is bad? How renal prefusion links to heart failure? What congestion is? You will.
You will go from a frustrated student unable to see the light at the end of the tunnel to a fully functional practitioner of medicine. And you wont even know it. You will still be struggling uphill, just to get a glimpse of the end, not realizing how far you've climbed. The summit is so far away, yet the ground below you is farther. If it feels like suffering. Suffer. The end result is worth it. You can't climb everest in a day, nor can you go from college student to the most highly trained post-graduate degree holding person in the country.
In reality, med school sucks. The first year is hard. Second year is harder. Studying for Step is the worst. But trust me, when you get on the other side of step, and you spend 12 hrs a day 6 days a week in the hospital, you will not only be happy to be seeing patients, but you will be able to communicate like you never thought possible. You will be thankful for it.
College is over. Med school is hard. You are part of the top 0.1% of the country. You are joining a field that requires the most training over any other. The longest degree tract possible. And you will be amongst the elite of the elite. Masters of the human condition, knowledge to a fault. Keep climbing that summit. On the way up, the view is terrible, and the terrain treacherous. When you are on the top looking down the view is simply spectacular.
