OK..... what can I say?
Everybody else's pretty much said it.

But, Don't get carried away!!
You know how you are, and how you
are able to research things.
OK, so hard is bad. There can be other reasons
not so bad..... find 'em.

As you said, a friend has had a thyroidectomy and
seems to be living OK with it. See her. Talk to her.

Go in the direction that everything can be OK.
You'll deal with it.(and hope the tests show
that it can be dealt with, easily)

We need you, Mrs D.
We want you to be well.

Go....Go away, and enjoy your vacation.
(I'm just sorry that you'll be out of touch for so long.)
