#1: Don't try to meet fellow geeks. Meet anyone and judge them on their personality individually. Maybe you want to socialize with non-LARPs once in a while.
#2: Leave your home. You mention "meat" frighteningly often in your summary, so maybe some cooking classes or taxidermy courses? Volunteer at a soup kitchen or something. Join a sports team or a game club or something. If you're fitness adverse, now is a good time to start. Classes at a gym are good motivation to exercise, and you can meet people.
#3: Make conversation with random people if you have a difficult time talking to normal people. Buy a coffee, make small talk as you pay. Talk to your butcher when buying meat. All this will help your confidence.
#4: Leave your home.
#5: Find singles events in your area. Bar nights, group things, etc, if you're interested in meeting people without the pressure of one-on-one.
#6: Leave your home.
Did I miss anything? Seriously, it's relatively easy. Just harden up and go out into the world. Stop letting fear rule your life. You'd be surprised how often you can meet geeks by accident these days. Everyone seems to have a bit of geekiness about them.
