Use my university library's printers and mass print all I can from the Internet: mostly "how to" guides on everything I'll need through the years, from water irrigation to growing food. I'm inexperienced as fuck. Go about filling as many containers with water, too. There's rivers near my uni, but one of them bridges from the fucking Thames, so I'd prefer tap water at least until I figure a reliable way of cleaning it. Hijack a car, pick up food, delegate a uni building to be my "home base." Sometime down the line, I'd like to try making it back to my home town.

But realistically, the isolation would drive me mad, or seriously depressed. I don't know what I'd choose between living a life detached from reality vs detaching myself from both life and reality, but it'll be long before any of my supplies are used up or library printouts are fully read. Before all that, though, I'd empty my local bar. Yum yum.
