What can i do when my entire life is crumbling around me?

Everything is falling apart around me .. i'm a whose in the closet with my family they are extremely close minded ignorant bigots, my gf is pretty much telling me that if my family won't accept her and us she wants to leave me, at the same time she already feels like she has a home with another woman eventho she doesnt actually live with her or been with her physically, i have noone to talk to and i feel we are hopeless even if i fight for her which im willing to do she will move to the other woman since she already says she loves her ( not as much as me) and things with the other woman are a lot less complicated.... people i need to hear opinions i just need to here your opinions about it and please no bad mouthing or bad answers i can't handle any extra burdens right now...
