*hug* I'm so sorry, Gina. I hope eventually she will come around, but from what you are saying she may not. Some of us are lucky and get to keep the family assigned to us at birth; some have to build a chosen family instead.
I hope you continue to build a support network in real life outside of your immediate family; no one should have to walk this path alone. In the meantime (and beyond), we're here for you.
Much love. *hug*
