i hate my work

you might wonder at the title.
here i was all happy with my work and the challenges involved, and all of a sudden, you see me complaining.
well, i don't exactly hate the particular work i'm doing.
what i do hate is what my work does to me and does not let me do.
i don't have the freedom i used to. most of how i spend my time is dictated by my work.
when i was in medical school (seems so far away, doesn't it? it's actually been only a little over a year), there was more freedom.
i could cut class whenever i wanted. i remember cutting class the whole day just to watch all three episodes of LOTR (lord of the rings) at a stretch on my friend's computer. or sitting and playing extremely out-of-date versions of need for speed.
those were the days.
now, i have to be inside theatre almost before others have to be inside the loo. and i have to stay there till the last patient is safely transferred out. and the good lord save the junior anaesthetist seen with a mobile phone or book in the hand inside theatre!
was just reminded of these things when a friend of mine was going through a tough time and i could not contact her because of all these constraints. at that moment, i really wanted to be with her, or at least call her. we could, and did, liberally cut class when a friend needed something back in medical school. now it's just not possible.
wonder if 'those were the best days of my life' and they really will never come back?
