Dear DDSLittleSister,
At this point in time, be there for your family as I am sure that they will be there for you. Don't take on any more than you can handle at the moment for you are in a vulnerable state of mind.
My brother passed in 1990 and we were 4 years apart also. What brings me a certain amount of solace is that I know he is never far away.
If you need to "speak", I'll be here.
Take care
God Bless
FTM
