this post, and your original one sound to me like huge cries for help, and I don't mean that in an antagonistic way at all. It just tells me that your not happy with where your life is headed, like you feel you have no control over the situation and that nobody is listening to you. I'm not a psychiatrist and I'm not trying to psychoanalyze you, it just sounds that way, because I think I can partially relate to what you may be going through (i could be very wrong however).
I took two classes last semester for fun, since I reapplied this year and I also found a great job full time, so its not to say that it can't be done, it just might not be what you want to do for the rest of your life, but I mean just like medicine, any career that you want to do will take some time and investment.
This break from school has been really helpful for me, its made me reevaluate a lot of things in my life, maybe it would do the same for you, because you sound like a very angry and frustrated person, and I agree with you, that if this is the way your feeling now, then maybe you shouldn't reapply. Your talking about studying for the mcat etc. etc. well guess what, EVERYONE here is going through some form of the same thing. If you want to succeed in life, you have to be willing to invest something into it, and to me, it sounds like you don't want to do that. So your either lazy, or maybe medicine really isn't your passion. You kind of hinted at it, but maybe your doing this for your family and not yourself??
