Wait is about all we can do, so why stress about it is the way I see it. It's frustrating not knowing which way your health is headed, I know that feeling all to well.
It's tough losing family, especially your brother. You mourn and it never really goes away, but it becomes less painful with time. Hang in there my friend!
Funny thing about waiting is that it seems too long when you don't even the end result of that waiting period, the anxiety heightens and we know we shouldn't stress about it, but it's probably the body's involuntary response to unsolvable problems. Things we really can't do anything about.
Probably very true!
