How do I deal with this?

This guy I had a huge crush on just told me he doesn't wanna be friends anymore. Much more happened, but he basically told me I make him feel uncomfortable by liking him I guess. I'm heartbroken. In the closet, I still denied my feelings for him bc I didn't wanna look stupid. Now I have to work my shift with him in the morning and it's going to be so miserable. I don't know what to do. :'(
