It's perfectly normal to have a range of feelings - including numb. I'm not sure if everyone has their own way of dealing with it. I think we're all pretty much forced into dealing with it in the same way.
Whether you're feeling numb, panicky, or anything in between, all you can do is ride it out.
And when you're feeling good, enjoy it to the max.
Time is on your side. When you started to have problems with your R, it didn't just happen over night. It took a long time. Things were going wrong long before you even knew it.
The same thing happens in reverse. Things start getting better long before you or even your H realize it.
That's something to keep in mind when you're feeling down. Much is happening behind the scenes.
So like KAW said, stay your ground. Keep a positive outlook, and wait for things to become tangible.
It's all happening, Sue. Just hang onto yourself until you can see it happening.
