What should I do if I [17M] think my crush is too pretty for me?

I have a crush on one of my classmate but she's like the prettiest girl I've ever seen and I think I am not a loks match for her. Im really confused on what to do and whether to confess. We have been texting a bit for like 2 weeks but isn't going anywhere but there isn't a complete lack of interest as well from both the sides. Please help a brother out on what to do
