Dating

The prettiest girl in my school keeps holding eye contact with me, but I don't know what to do! Please help?

I'm a senior in high school that hasn't had any dating history at all. Never held hands romantically with a girl, never hugged a girl that I liked, and I only kissed a girl in elementary school. A lot of girls have had crushes on me, but because girls still feel like guys should do the approaching and me being very shy, I've never dated anyone before. Now onto this girl. During lunch, I'll see in the corner of my eye her looking at me and sometimes when I get eager, I'll look at her to assure that she's looking at me, and sure enough, she is. Whenever she starts at me, my mind starts racing and I start asking myself, "why is she staring at me? Does she like me?" And I always answer those questions with, "there's no way a girl like her would ever settle and like a guy like me when she can gave any guy she wants, I mean, what's so special about me that she'd like?" Some of you are thinking, you're not as ugly or dumb as you say you are, you're self-esteem is just shot." I admit that my self-esteem isn't too high, but even if I did have a good self-esteem, Id probably still wonder why she'd like me. I'm only 5'6", I'm kinda smart, but not top 10 kind of smart, I'm shy, which I've learned from experience, girls do not like, and from a scale of 1-10, I'm a 7 max. Not to mention I have moles on my face. So with all this taken into account, why would a girl like her be staring at a guy like me? There's no way she likes me, right? And even if she did, what would I even do? (I know, I'm a pathetic little boy with no self-worth, just please don't call me out too much)
