At the 2013 Human Rights Campaign Dinner in Seattle, Washington, Miller said he had attempted suicide multiple times as a teenager before coming out as gay. He said: “When someone asked me if that was a cry for help, I said no, because I told no one. You only cry for help if you believe there’s help to cry for.” He discussed struggling in Hollywood as a closeted actor, and talked about how his involvement in the ManKind Project helped him learn about brotherhood, sisterhood, and being part of a community.
