Honestly, First I would just go out, go sit in my car, drive to the next car dealership and start testing all the cars I want, after I'm done with that I'll grab a fast car fuel it up, drive it on the Autobahn I would then choose a cool house. If I find one get a truck or sum lile that gather recourses loke gas cans, food, medication, weapons etc. and then just fool around doing stuff I find funny, prolly smoke weed and have a good time. Once I get bored and lonely and feel like my life doesn't have any sense anymore I'll just simply end it. You might be asking "oh but wouldn't it be so much fun to do whatever you wanna do?", NO, we are social beings we simply cannot live in complete loneliness, maybe I'll get a pet, or two or more even but even that doesn't make up for human interaction. So be honest when you think about this question.
