Recurring kernel panics for the past 6 months - help!

HI all,

So I purchased a non-manufacturer refurbished mid-2010 MBP about 6 months ago. It came with a 1TB hybrid SS/SATA drive and way more software than I will ever use(i.e. entire Adobe suite) but basically since I got it it's been restarting intermittently; black screen, restart, "your computer restarted because of a problem." It seems to particularly hate switching between apps (especially with Mission Control) and occasionally when composing a new email in Mail. I ignored this for long time because I was a new Mac user but it is pretty **** irritating not being able to switch between apps easily or compose an email without restarting. It also gets ridiculously hot so I have temperature and fan control app installed that works pretty well; the hottest I've ever seen it is 92 degrees and the trackpad stopped working, but was fine after an hour or so of being switched off (I'm not sure how relevant this is, but additional information can't hurt right?)

I check for updates daily; I've reinstalled from Time Machine and the problem is still there, and it carried over from Snow Leopard to Mavericks. I've seen some people recommending deleting drivers but I'm reluctant to interfere with stuff I don't understand for fear of breaking it completely. At this stage I genuinely cannot afford to get it fixed - I'm afraid that any Genius recommendations are going to be pricey and/or ineffective, so I'm open to suggestions. Here is the most recent kernel panic log;

As a student I'm relying on my Mac for absolutely everything. If this can't be fixed then I'd like to know if it's going to get any worse, but if anyone could help me decipher the log and/or suggest a fix then I would be eternally grateful! 🙂
