I play the same way, I used to have friends on Neopets when I was younger, and sometimes I'll befriend someone out of the blue on a very very very rare occasion... but tbh, the game is a lot more fun without the social aspect part of it. I like hanging out here during work and stuff, because I'm high. And sitting in a room playing with kittens. How much easier can a job get, there has to be 'something' to occupy my time!
You're not a loser for not having Neofriends, it just might mean that that particular aspect of the game isn't as important to you, but seeing other people who have bonded friends on the site might make you feel guilty by proxy. Like you're missing out on something.
No worries though! :3 There's nothing wrong with not having Neofriends. I keep my friends in the real world as a higher priority, and the internet is just all fun and games!
Enjoy what you like to do on your own terms, but if you want friends and solace, maybe just keep someone who's got a level head and roots outside of gaming as your friends. I don't know if I'm making sense.... but uh, the game is fun to play, but the friendship part of is isn't as important if that isn't your priority.
