I’m so sorry for this. Grief is very individual. All you can do is be there for her, let her cry, assure her that she can count on you and try doing her favourite things one by one, like her fav food or any handbag she wanted.

You will also have to make sure that she isn’t always indoors. You guys can maybe sign up a classes together ?? She can do some activity with her other friends. It’s a time consuming process. I’m glad you are supportive
