Is it normal to have conflicting thoughts towards my self-confidence?

I am a guy with contradicting emotions. I guess this will sound really awful, but I kind of hate people. Maybe I am just rather unlucky, but truly, every person around me is a horrible human being.

I guess that this makes me feel sometimes better than others in certain way. So this would be one of the positive points for my confidence, I feel that I am better than most people. But there comes a negative point, I feel like an asshole for thinking that way.

And pretty much almost everything good about me has a negative side. For example, I believe that I am smart and handsome... in an average way. So even though I cannot have complaints in this matter, I know that I am the kind of person that mixes in the crowd.

The most noticeable consequence of this appears in my relationships. I have really low standards when I choose who to date, because I don't consider myself good enough for most people. But as soon as it gets serious, I feel like I could totally get someone better. So pretty much, I never enjoy any relationship.

So well, that was my ramble for today. So, is it normal?
