Help please anyone

Recently my SO told me that they didn’t know if they were in love with me anymore b/c they couldn’t feel anything towards everything. Like she said when she watched something that she’d normally laugh at, she did the opposite. She says she hasn’t been able to think clearly and she can’t tell what she’s feelings. The day that she told me she didn’t know broke my heart and I still couldn’t stop crying and I’ve been doing my best to hide it from her so I can help her out with her situation. She said in a week that she’d figure out what’s wrong and if she still is in love with me but until then I just keep getting more hurt Bc I can’t eat, sleep, or think. I don’t know if it’s her feelings or if she’s just stressed and I don’t know if when she goes back to her normal self that I can be my normal self for her.
