Thank you, everyone, for the love and support. It means a lot. We are all stunned by the diagnosis after DD seemed to be doing so well post-surgery but the important thing is to support DD, her partner, and the children so that's what we will do one day at a time.
soop, I think DD will love to receive the card. Just cross out the get well soon bit or paste something over it and thank you for organising it.
Last night I put a terry facecloth on my pillow to catch the tears that flowed as I settled down to sleep. I think I will need to do that quite often.
