Help my best friend. Please.

Help my best friend. Please.
I need help. My best friend, Virgil, is on a very toxic place at the moment and I want to help get him out of there. He's currently being forced to go to a high school that his ex girlfriend and abuser goes to as well. He's stuck with her for hours a day as she appears numerous rumors about him. I've been in his place with the same people so I am very worried about him.
He has had numerous rumors spread about him, people have been Transphobic to him, and others. He has told me several that he doesn't feel comfortable being there and near her. She hurt him to the point he tried to k*ll himself and had to get sent to a mental hospital.
Me and a group of friends are trying our best to help him by trying to get him out of that school and transferred over to my school. I can't just stand by while I know that this is happening and he's hurt by it.
Please..I really just want to help my friend. I can't lose him.
