I'm sorry your mom was so unsupportive. That must have been pretty crushing. I don't even know what I would have done if my mom had reacted that way when I told her. She was as understanding as she could be, and still is. She doesn't totally get it, but she tries. My dad is old school and just calls me "goofy" which in his weird hick vocabulary means crazy. He's at least not openly unsupportive, he's just not supportive either.

I hope you're able to find a therapist or a friend you can talk to about this, and you're of course welcome here. You'll find lots of support here.
