How can I get rid of this crush?

I 25f have a massive crush on 29m coworker. He's so sweet he's timid and shy but he's just so damn adorable and handsome. The fucking man has infested my damn dreams at this point I think about him constantly. Don't get me wrong he's single but he deserves way better than anything I could ever be for him.

What can I do to kill this damn feeling and no I can't avoid him we work next to each other
