Dude stay in, its only 1 year of your life i mean, it wont hinder u at all just to stay one more year, you can only gain from that. As for socailizing, moving in with a random person most likely will grant you more friends, meeting random people is how u get friends. Start going out to all the parties people have (if your wanted there) bring some nice chron and share it with everyone and talk and make friends and then when ur done college, you can relax and atleast you will have SOME more options.
