As a mother of 1, working full time, trying to squeeze in more work experience, and studying for GAMSAT, I think we could all benefit from some time out!
Up until about a week ago, I was studying Physics in my lunchbreak, and and hour of chemistry in the evenings (once I'd collected my little one from nursery and got him to bed). I was also working compressed hours (so full time hours squished into 4 days) so that I could spend Friday's helping out in my local hospital. I found my self completely burnt out, unable to sleep properly, ill all the time, run down, and with my head so full of science, I couldn't string a logical sentance together. :?
Last week I found myself feeling really depressed about the whole thing, and was bursting into tears at random moments for no reason! :?
Anyway, this last week I have had a complete break from the science stuff, written a couple of essays, but have generally given myself some breathing space. I'm now feeling much calmer and as a result feel like I can cope this nasty Grimsat afterall, and maybe even do well.
Moral of the story - give yourselves a break. 
We're all intelligent people (otherwise we wouldn't be here), so you can afford to have a week of letting your brain soak up the copious amount of information you've been chucking at it! I guarantee you'll feel much better for it.
