Really bad situation

Hey everyone. First of all, please don't judge. I had a test day for work on Thursday. And the daughter of the boss helped me that day. She's just one year younger than me, and omg. She's the prettiest girl I've ever seen. The downside? She has a boyfriend. AND I obviously wanna work there, so this can't be a thing for multiple reasons. I just can't get her out of my mind. Has anyone any tips on how to overcome this? Or maybe some songs that talk about this kind of thing? Would greatly appreciate it.
