I have ugly duckling syndrome... How do I go about dating?

I recently got "pretty" and started modeling and getting a lot of attention.. But I really grew into my looks.... I'm 21, and I used to be a huge tomboy. Everyone always told my sisters they were pretty and it took me time to blossom it seems. But now people tell me I have so much potential and have surpassed expectations and am so gorgeous... and I just don't know how to feel. Sometimes I just think it's all so stupid, who cares about makeup and stupid "stylish clothes." I feel like the raw emotion of the picture is enough, no matter what I'm wearing. (Half the times, it's so fashion forward I feel like a freak! And not confident at all. Yet it's my livelihood to depict that I am all of the above.) As a result I feel like I attract a lot of unwanted attention and it complicates my dating life. What do I do? How do I date like I've just started when I'm in a cynical and turned upside down world??
