Cover art for Miss You lyrics by Foster the People

Pretty certain it's about a guy who purposefully overdosed on drugs to kill himself. He's reflecting on a past love as the drugs kick in:

"Lay it down, they start up" "I'm all spun and pacing" "I never knew that I could go as far as this" "Feverish and peaking, just want to see your face"
