Born on March 15, 1987, Myrick has three siblings. Myrick's father, Jessie, is black; his mother, Leslie, is white. During his infancy, Myrick and his family experienced periodic homelessness. Jessie Myrick's struggles with drug addiction (specifically, an addiction to crack cocaine) led Leslie Myrick to move her four children from Florida to Earlville, New York, a small village of 900. Myrick was raised in Earlville by his mother and his maternal grandparents, Wilbur and Phyllis Raville. Myrick's family struggled to get by and depended on food stamps, with Leslie Myrick working multiple jobs to provide for her children. Myrick attended public schools and graduated from Sherburne-Earlville High School in 2005. He had asthma while in high school.
