My wife and I went through a very tough period after I told her, but you can get through this. You have just turned her world upside down and she likely doesn’t understand her feelings. Give her time to reflect without adding further unsolicited discussion on the topic.
I recommend that you pay her extra attention and show her how much you love her. She needs to know that your relationship is no different than it has always been and that you are still the same person she loves.
Good luck
