The GoFundMe for Wersching's loved ones was created by Handmaid's Tale actress Ever Carradine. It's set up with a goal of $250,000 in order to allow her husband and kids to "grieve without the pressure of needing to work." "She wanted to protect her boys. She wanted to get better so she could continue working. And honestly, she just didn't really want to talk about it. She wanted to live her life, on her terms, and be with her family," reads the fundraiser description. Full announced his late wife's death in a statement to Deadline. "There is a cavernous hole in the soul of this family today," he said. "But she left us the tools to fill it. She found wonder in the simplest moment. She didn't require music to dance. She taught us not to wait for adventure to find you. 'Go find it. It's everywhere.' And find it we shall." "As I drove our boys, the true loves of her life, down the winding driveway and street, she would yell BYE! until we were out of earshot and into the world. I can still hear it ringing. Bye, my Buddie. 'I love you, little family…' "
