Strict mother

Hi! This is less a confession and more looking for advice... I'm trans, but my mother refuses to accept it. She says that I "don't act like normal boys" and that I'm just trying to hide the fact that I'm a lesbian (even though I'm aro/ace) or trying to hurt her. The worst part is, I'm stuck with her for at least another two years and probably more and I'm scared to go to anyone else for advice. She's incredibly strict and I'm hardly allowed to do anything. I'm scared and upset... What can I do?
