I'd also say, never ever ever feel bad about yourself, if you feel you don't quite 'gel' with the world, or you find yourself at odds with the world.
The fact that you do feel at odds with the world, actually means you're quite sane (though perhaps a few people, who are so conditioned by the mechanics of society, won't see that, but in reality, they're the ones' who are lost).
Trust and follow your inner guidance..
All the best,
Jamie.
