It really does bother me so much when people, especially when mental health officials/experts tell me, "There is nothing you can do."
One person even quoted a part of the serenity prayer to me while I was explaining the pain I was in about my son's illness and recent setbacks. He referred to the part which says, "Accept the things I cannot change."
Thankfully, I'd heard of a quote myself, by someone else who must have been told to just accept what is. I repeated that quote to him. “I am no longer accepting the things I cannot change. I am changing the things I cannot accept.” (Angela Y. Davis)
This has truly become my mantra.
