Find a couple of Dogs and train them to be my attack dogs/pets, learn how to use guns and also have a distress beacon going, just in case. If any bears or anything got too close to my home (a converted bingo parlour)i would just shoot them in the face. As for entertainment and stuff. Minecraft would keep me going and i have almost every Yogscast video on a flash drive. With out online multiplayer, i wouldn't use my consoles as much though. And i'd try to get every movie availiable to me in my house too. Also i'd keep a journal of sorts, simply just to keep me sane and to stop me questioning my own excistance. I would also develop an AI companion, Just as sombody to talk to besides the dogs. Then after doj g all i can to survive and such, i would just wait until the inevitable end...
TL;DR Version
Get Food
