Hugs to you LA.
Receiving a diagnosis of anything bad is a shock. Having your suspicions of many years finally heard and seen is a relief, but it puts the same stress on your body as the bad news does.
It's a very hard thing to do, but try to breathe deep for a few days and relax. Now that you know what is wrong for sure, you can take steps to start on this split in the road.
You're not alone! ( but then, you know that since you are here!
