At least you are honest yourself and - unlike many others whom I've run into - don't pretend that you are excited for something that isn't truly that exciting. I know a lot of people who will pretend that they actually enjoy sitting in bio lab for 6 hours using a pipet in fear that if they don't act 100% excited about it, they won't make good doctors or something.
LOL, there are people who do enjoy that, but if somebody does not enjoy that, it doesn't say much about whether they should become a doctor because being a doctor isn't very similar to pipetting, last I checked.
However, a love of learning is one of those attributes that would be important, if not essential, for being a doctor.
I agree that medicine is starting to not look so great for me as well, for a few reasons:
1) It requires more schoolwork, more classes, more needless competition, etc.
I enjoy schoolworks and classes, except during finals week. Competition would depend on what speciality you want to go into, and what school you go to.
2) It entails a life of toiling (which makes a simple 9-5 job look pretty nice)
Hard work is rewarding if you enjoy what you're working at. And I don't think every specialty requires much more than 50-60 hours. I've met doctors who work part time (<40), but it's rare and not usually possible.
2) Most doctors (whom I've met) don't seem to love it too much
All but one I've met wouldn't want to do anything else. Perhaps some go into it for the "wrong" reasons, e.g. money.
3) I don't like most of the other people I see going into it
That said, please don't listen to people who say "Well if you are losing your passion for being a doctor, you better reconsider." Perhaps you should reconsider, but not based off of some loss of a nebulous "passion" (a word that doesn't really mean anything). None of us can really know for sure whether or not we will enjoy or have a passion for doctoring, because we haven't been doing it for 20 years.
Well another consideration is how long these feelings persist. Everybody feels off or down about everything sometimes. Every now and then nothing in the world sounds fun to me, but I shrug it off and it only lasts a day or two. If these feelings persist for months, however, then you need to consider that you have a problem. I'd put off doing anything hasty prior to July, to make sure this isn't just a symptom of burnout or a passing bad mood.
I think for the time being it would be best to look at the realities surrounding your situation. Think about what truly drew you to medicine: is it academia? money? people? job security? An (as always) be honest regarding the reason. If you find that you can get those things with some less intensive line of work, then perhaps you should reconsider (I am in the process of doing that right now). However if you have needs that are only satisfied by a job in medicine, then put up with it in hopes that things will get better.
Yeah, I doubt many people who go into medicine love everything about it, but if there's no better alternative, then I'd stop trying to expect your job to be utopian. It's like expecting your marriage to be perfect. The more you expect that, the less perfect it will seem/be.
Another thing to consider (which a lot of people here seem to forget), is that - as cliche as it sounds - you aren't defined by your line of work. Too many pre-meds make the mistake of feeling like their future and persona are competely dependent on their major/career/etc. But really people are people, and most people won't end up deriving happiness from their line of work anyway (personally I think happiness comes primarily from interactions with friends/family/lovers). So... you know, don't fret too much over the decision, you'll still be the same person (and probably end up happy regardless).
Yes and no. It seems medicine is something that has a greater tendency to define people because it takes up more of your time than most careers.
I hope that helps. Don't feel bad about your doubts - it is good that you are having them; it's the doubtless ones ("I know for 100% sure that I have a passion for medicine) who are obviously clueless.
Well it isn't the worst time to have doubts. After classes start your spot cannot be filled by somebody else who is sure, and after years in medical school you'd be stuck with hundreds of thousands of dollars in debt. So if there are doubts, now is not the worst time to have them and address them.
