The Trevor Project, a nonprofit that works to prevent suicide among LGBTQ youth, interviewed more than 28,000 people for its annual survey.
More than 40% of LGBTQ youth say they considered suicide in the last year, the survey revealed.
Respondents said laws passed on the state level, and public lobbying at the national level, have worsened their mental health.
"This is a public health crisis — and it's preventable," Kasey Suffredini, a vice president at The Trevor Project, said in a press release.
Almost a quarter of the LGBTQ youth surveyed said they had been physically threatened or hurt because of their sexual orientation or gender identity.
