Ahhh, bless you Bridget. I am so sorry to read of the loss of your father-in-law. I agree with what you say of MM – yes, there is time to gather thoughts and wishes versus some other cancers that cause such a rapid decline sometimes soon after diagnosis.
I can't imagine the emptiness your mother-in-law will be feeling after all those years of togetherness, I'm sure your father-in-law will be by her side just now even though she can't see him …. maybe a familiar smell, a tickle on her cheek or electrical interference (usually TV or a kettle), they had so long together after all he won't want to be heading off on a new adventure without her.
I don't know you personally, but can tell from your posts you are the glue that holds your family together with your wonderful support and advice …. I pray you are sent guidance, support and strength to see you and others in the family through the coming days, weeks and months. Bless you all.
Sent with healing thoughts and love
