A no from your crush isn’t a ruling on your worth. It’s one person’s preference.

Attraction is specific and not especially reasonable, so a no mostly describes the other person rather than you. They have their own taste, their own situation, and possibly somebody else entirely on their mind. Treating that as a measurement of your value hands one person an authority they never claimed.

Let it hurt for a few days without turning it into a conclusion about yourself. Stay normal with them if you share a class, which is easier than it sounds and quietly earns respect. Then put your attention back on the people who are glad to see you.
