Mr Marquez, 21, suffered severe burns to his face, neck, arms and back that required skin graft surgery. His 23-year-old boyfriend's burns were so extreme across his entire face and 60% of his body that he was put in an induced coma and has just been released from hospital.
"The pain doesn't let you sleep. It's like excruciating, 24 hours a day and it doesn't go anywhere. It doesn't dial down or anything. It's just there," Mr Marquez said on Atlanta's WSB-TV.
"You wake up in the middle of the night, you just cry because you want to sleep and you can't."
