I rarely listen to happy music. When I was a teen I listened to billboard music. They made me feel carefree. I was depressed but I wouldn't allow it to surface so it was a good medicine, then. They made me think problems didn't excist in my life except the lyrics of the songs on the radio.
I'm less 'happy' now but I never miss those times. They meant nothing, just like the songs on the radio. Maybe that's my advice. Turn on the radio..
