Need some advise

An

Now I know this channel is mainly for postpartum but I could use some help. (If anyone experienced depression or anxiety before birth)

My sister is expecting her first baby. She is due at any momento now but she is already having some sentimental emotions that are affecting her pretty bad. She doesn’t want to eat or walk and she is crying all the time. Now, before you say I don’t know what she is going through, I am a mom myself. But I did not experience what she is going through now. All I’ve been telling her is to cheer up that her baby is almost here and just once she sees her everything else will be a blur.

I tried taking her to eat her favorite food or look at baby clothes and things like that but it has not helped.

Any advise?

Kindly appreciate it.
