Happy birthday despite the chaotic feelings!
My husband went to the doctor in early July. Even with all the tests, we never heard a definitive diagnosis until mid August, we heard some preliminary at the beginning though. It was a slow process.
Lots to learn here and these people know the ropes. My husband does not ask questions and does not do what they tell him to do to get through his treatments as well as possible. He has paid the price for it. I say listen to the experienced!
Best wishes for you on all this.
