To constantly feel incompetent

I grew up in an incredibly competitive and affluent community and never quite fit in. Now, I'm in my freshman year at a university. I have made very few friends. In terms of relationships, girls here express no interest in me. Most of the time, I feel completely incompetent. I'm attractive (from what people have said), tall and thin, but all I ever see is ugliness. I won the "best dressed" superlative at school, but I feel like a clown when I get dressed. I'm socially awkward and have a strange sense of humor. The few people who are intrigued by me often walk away bewildered or uncomfortable. The worst part about this is that when I tell people of my woes, they tell me how my vision is skewed. How can it be skewed? The flaws I see in myself are/seem completely real.

I dunno.. you tell me
