I know how you feel and I am so very sorry.
You might remember that at the end of January I got into bed at midnight as usual with Bubbles and Holly P. Also as usual, Bubba and I snuggled up to watch the midnight Sky News, then I put the light out to go to sleep. I woke up at 3.55 a.m. to realise that Bubbles wasn't breathing. She looked so peaceful I am sure there was no pain and I chose not to have a P.M. I wanted to bury her as she was.
I'm very sad to say that sometimes these things happen for reasons we are unlikely to understand. You are in my thoughts and prayers.
