Alright, I really hate getting dragged into these kinds of threads, so I'm not going to belabor my point beyond this post.
I'm just saying... let me know when you find the magical mythical job where you get paid lots for doing little, that you feel satisfied for making a difference at the end of the day, AND that you find intellectually stimulating. Because I'm pretty sure it doesn't exist, and that no matter what profession you go into, there will be reasons to both enjoy it and reasons to wish you were doing something else. So you might as well accept that there is no "perfect" job out there and settle on something that you think will be somewhat more interesting, enjoyable, and profitable (in whatever order matters most to you personally) than your other options. If you get there and find that it isn't what you thought it was going to be, then you should either do something about it or learn to live with it.
I can agree with you that there are several reasons why one should not go into medicine, and there are many people out there for whom going to med school would be a bad decision. Some people would do well to consider what they're getting themselves into more carefully before jumping in. But to seriously imply that EVERYONE who goes into medicine winds up cynical and angry at the profession is a gross overstatement, and to say that EVERYONE going to med school will regret it just because you do is overtly arrogant. I don't have to finish my second year to know that, because I'm perfectly capable of talking to the 4th years, residents, and fellows at my own school and know that, contrary what some of the "experts" in this thread would like to imply, the majority of them are still quite happy with where they are and are going in life--including the student who scored well above the national average on her Step I but is still CHOOSING to go into family medicine, for example, and is extremely excited about starting next year (since we seem to love anecdotal evidence around here).
I firmly believe that people, to a great extent, make their own happiness and unhappiness, and it has to do with how you choose to look at your current situation. Sucks that you're so unhappy, but maybe you should try and do something about that yourself rather than preach to a bunch of people who you don't even know and tell them how their life is going to play out.
