Is there a meet.up in your area? I've joined many vegetarian groups so I hang out with people who do not think someone who doesnt drink or use animal products is "boring". It's easy to feel like an outsider but for me, picking up a drink never really made me fit in. It's about being honest with my peers. A lot of people really respect the fact that I don't drink. They think it's cool that I don't harm my body anymore. If they dont respect it I don't spend a lot of time with them. That may sound harsh but honestly I just find it boring to watch others drink, I have better ways to fill my time.
