Okay kiddo, let me explain something really sad that's been happening to some people who are both part of the Mormon religion and identify as LGBT.
The Mormon religion believes that homosexuality is wrong, which means they don't support people who love someone of the same gender. This can make some people who are LGBT and also Mormon feel really bad about themselves, like they're not worth anything or that God doesn't love them.
This feeling is really hard to deal with and it sometimes leads to these people feeling so sad that they might even want to take their own life. That's what a suicide is - when someone decides they don't want to live anymore and hurts themselves because of it.
So, some LGBT people who were also part of the Mormon religion felt so sad and alone that they thought suicide was the only way out of their pain. It's a really sad thing and we want to make sure that everyone feels loved and accepted for who they are.
