Forced to hide her true self, Joe Horras’ transgender daughter struggled with depression and anxiety until three years ago, when she began to take medication to block the onset of puberty. The gender-affirming treatment helped the now-16-year-old find happiness again, her father said.

But now, a decision by the U.S. Supreme Court allowing Idaho to enforce its ban on such care for minors could jeopardize her wellbeing once again. Horras is now scrambling to figure out next steps and is considering leaving Idaho, where he’s lived his whole life, to move to another state.

“It would be devastating for her,” Horras, who lives in Boise, told The Associated Press. “If she doesn’t have access to that, it will damage her mental health.”

Horras is among the Idaho parents desperate to find solutions after their trans children lost access to the gender-affirming care they were receiving. The U.S. Supreme Court’s Monday decision allows the state to put in place a 2023 law that subjects physicians to up to 10 years in prison if they provide hormones, puberty blockers or other gender-affirming care to people under age 18. A federal judge in Idaho had previously blocked the law in its entirety.
