I see that you like art, singing and spending time with your family. Use these things to occupy your time so that you aren't sitting around thinking about this guy 24/7 and getting depressed.
Turn the music on and sing. Go get some art books from the library and read them. Do you paint or draw? Do that. Go do something fun with your family.
Get creative and get your mind off this guy. Over time he will be in the distance and then completely gone out of your mind.
STAY busy......do that.
