Is art college supposed to drain you?

I'm gonna try and not let this turn into a whine-fest, but Jesus christ. I only go 3 days a week but this somehow manages to be more exhausting than highschool, which I attended monday to friday (obvs).
It's probably because at Tafe I'm an adult who is expected to take care of herself and I tend to forget to eat (Unless milkshakes count as food. Do they? They got icecream in 'em.)
