I've set up a variety of WhatsApp groups at different points. One message goes to all, very useful. I got my husband to deliver info and news when I didn't want to or feel able to. Everyone seemed to understand and was respectful. With the exception of my sister who felt the need to abuse and criticise me from her holiday in New York when I had just finished chemo and was preparing for my bilateral mastectomy & reconstruction. I blocked her on our private channel. Now she can only communicate with me on the ones we share with other members of the family. No abuse so far...
Someone is pretty much awake here at anytime of the night. So don't feel you have to cry alone. There's a thread called Who else can't sleep? that @Sister started ages ago. It has many contributors! Big hugs, K
