6 year relationship

On a 2 week streak at the moment, (my wife) won’t even look at me half the time, very short, blowing up at everything, saying I don’t ever listen and everything’s about me, how her life sucks, etc etc, i asked her to please set up a appointment with a physiologist as this is the worst it’s ever been, she said I will but I want you to know I don’t even know if I’ll still love you or want to be together once I learn who I really am etc, and I got slightly upset and she said how do I know if I’ll still love you if you I’m not really myself with this condition etc, and she’s mad I got slightly upset by that being brought up, I’ve dealt with consistent things over the 6 years as I love her to death when she’s not in her moods, and now I may be thrown aside once she’s better? After all the years of putting up with the crap? That hurts
