“I started talking about it with a couple of my close friends and family about a month ago and it’s given me the courage to start the process. I feel like the next step is to tell all y’all. So here goes. Love it or hate this is who i have been for a looooong time. I love u guys. Talk sooooon byeeee,” Geiger added.
