I have a crush on this girl and I don't know what to do

Alright so there is this girl in my highschool i only have one class with her and she's on my bus I don't really know much about her other then her name and people she talks too I'm not that well liked at my school so I'm kind of worried about that I don't even know if she even likes me at all I've never really talked to her or interact with her or anything like that and I don't have her number or social media or shit like that I'm always kind of scared to even interact with her (Everytime she even looks at me for a second my heart skips a beat)

What do I do? Am I cooked or?
