Thanks everyone.
I've always dressed in male clothes, had short hair, and have a relatively deep voice so I do have a few things working in my favor at least. I also have no real contact with the rest of my family outside of my father who is rarely around, I just have this crazy idea in my head that my mother will find out and I'll end up homeless. I might be moving in the fall and that would be a godsend, I could shave religiously for 6 months haha.
