In love with a straight guy :(

Honestly, it's usually easy for me to get over crushes. But there is this is one straight guy, who I just love.. I just used to have this on/off crush towards him, but it's just worse now. Like, I can't even be next to him without feeling depressed as shit! Every second I am with him, I just feel gravitated towards him. I've never had such intense feeling before..Any tips on getting over him?
