i think for the most part i am happy having chosen to go to med school and the med school i've chosen to attend.
yes, we bitch often and have to deal with tons of red tape and sometimes feel that this is an autocratic stronghold with no room for levity, but it's not like that all the time.
if someone is miserable day in, day out, then i agree with the previous post that person may have gone into medicine for the wrong reasons.
if you have a passion to learn medicine and to become a physician, then all these obstacles seem frivolous (yet tedious) and you surmount them without much scarring.
there is something always to remind you why you've chosen this path and that you're heading in the right direction...it can be a compliment from an attending, a smile on a patient's face, or a thank-you from a nurse or someone from transport. those reminders efface some of that dejected feeling i think we all get, that things are too rough, that there's no way to juggle every task assigned, no way to make your domestic and social life compatible with your medical life.
look around for the reminders, the sources of reassurance, which may often be subtle. when you find them, then struggle seems lighter, maybe now just a challenge, but not an impossibility.
