My mum lost her mum (my grandma) on Friday and she keeps telling me that she's okay. She did cry on Friday when I cried and every now and then but she keeps telling me she's fine but I know she's not because her relationship with my Grandma is exactly the same as mine is with her. We were all very close and it's like my mum has lost her best friend.
How can I support her when I'm very sad myself?
