Oh Etta, I am so sorry to hear your news and for the loss of your sister. What a difficult thing to face when you are dealing with myeloma yourself. But you don't have a thing to feel guilty about, life can be harsh and we have no choice but to play the cards we are dealt.
You have not rambled at all, but feel free to ramble as much as you like if it helps make you feel better. This forum is full of great 'listeners' and we are all happy to do anything we can to help.
Be kind to yourself at this time, take life as easy as you can. My thoughts are with you and all your family,
Much love Mari xxx
