How to comfort your depressed wife?

I can't make her happy no matter what I do I always ask her what she wants she says she doesn't know. I feel so I'm a bad husband because I can't help her. She said she doesn't want help she only wants me all she does is cry which really hurts me I love her so much I'm worried she's gonna end up hurting herself. I've been with her for 2 years we been married for a month before this virus started she use to be so happy I don't know what made her this way I hate seeing my baby girl so sad knowing there's nothing I can do for her. How can I comfort her through this? What should I say to her?
