Oh, Shirley, Bless your heart. (Yeah, i’m a Southerner.) Losing one sibling was hard, I don’t know if I could stand up to losing so many.
I’m gonna be praying for you, and for your remaining brother, and especially for your mother. Take care of the family you have left, and especially take care of you.

I am very sorry to hear about your brother Shirley. Hugs to you.

Shirley, I cannot begin to say how sad this made me. You have my deepest sympathy. To watch so many loved ones leave so soon is beyond my comprehension.
I hope any suffering is at an end and want to think that someone so compassionate as you will not punish yourself in any way. I can only say to celebrate their lives and do not grieve for them. Have a party and remember all of the love.
I’m totally blown away.
My condolences Shirley. I can’t really say much more than what Poly’s said already and much better than I could have.
Damn.
I’m sorry.
Have my virtual hugs and my real condolences.
