I was really bad antisocial when I started playing. (I have literally one friend irl..just to say how bad I am. lol). Just randomly apply into an FC if they're recruiting via shout. Just ask what do they mostly do..are they active, do they do mount farms, are they small? Join a random one. You don't have to talk or even be active. You can always just leave. Every FC that I been with has understood that not every FC is going to be a 'fit' for someone. If you make one friend from any, they'll almost always ask you if you want to run something with them and their friends. Before you know it, you have friends! I also tend to randomly ask DPS'ers if they would like a que skip if you see them waiting on the Duty Finder. That's another way to meet people if you have a healer or tank.
