Wow. What a kick in the gut. I don't know what to say except I'm sorry and I dont think it is helpful for your sister to try to get a reaction from you. Sending you virtual support.
I hate it. Grief counseling and regular counseling help me. I have control issues that trigger guilt in how I hande this new life. I am able to let go of my "I couldn't save him" guilt. It is a blessing.
Im so happy for you enjoy it.
One of my favorite lyrucs from Dave Matthews band
"Troubles they may come and go,
But good times they are the gold.
And if this road gets rocky girl,
Just steady as we go."
