I'm thinking of you and your family and friends Val.
I'm so glad that at the last you got your "old" Mike back and that's one of the better memories to hang on to.
The knowledge that, at last, he was able to find some measure of calmness and relief I hope will give you some comfort.
As others have said, you've had to be strong for such a long time and you'll need to be strong for just a little longer although I hope your pain has eased knowing that Mike is at last at peace.
Best Wishes and virtual hugs along with the virtual support
Sandra
