Yeah, I know how you are feeling. It's cathartic to vent, so vent away.
This disease and all it's incumbent fears are horrible. Just try not to let yourself slide into that grave . You really do still not know exactly what you are dealing with here. But I get the worries and fears. Try not to borrow sorrow from tomorrow.
Why do they want to wait 6 weeks more? If this was "us" I would want a definitive answer and start of treatment now.
Keeping you and your Wife in my thoughts .
