🎶Yesterday, All My Troubles Seemed So Far Away🎶

People are well meaning, but how do you answer the question.
"How are you doing?"
Not possible to answer that in a way that's truthful without making other people uncomfortable.
I feel like screaming, like I want to pound the walls, lose it completely...
How do you deal with news that it's cancer most likely stage 4 and yet,you have no answers?
Don't know the type yet.
Have to wait on tests and appointments.
Don't know what treatments they will do.
How do you deal with it?
Deal with people wanting comfort for themselves when all you can manage to do is to keep yourself sane long enough to not lose it?
