Kay sounds like such a magnificent spouse! She is probably just as happy to be taking you as you are to have her by your side.
You are blessed for sure. This is merely a bump in the road and once you get started with this new battle you will fight the beast and win once again.
We are here for you in any way you need us. To lend an ear, cheer you on and pray for you.
Please do let us know the results of the MRI. Sending you warm hugs.
