Her dh died suddenly. We've not seen each other for many years and I didn't really know her dh. However, she was a good friend and we're still in regular contact FB, WhatsApp etc... Just sending a card doesn't feel like enough but anything I think to send her seems trivial or contrived. I plan to visit her later in the year, if she is keen but don't know how to show support in the meantime. She has masses of friends and family local to her, so isn't short of practical support.
