Hello Blue Sea
well, what I would say is first that I'm sorry for your loss. It is never easy, is it, even in these circumstances.
I'm pleased you could be there to the end and see it was untroubled.
I'm also pleased for your relief!
The last thing I would say - please don't take this the wrong way - is "that's the way to go"
I'm going through many of the things that you have been through. Jan will leave a hole in my heart and my life when she eventually passes on. However, if she goes as did your Dad, that is how I would choose it.
And I would rejoice in her memory afterwards, and the knowledge that her trial is over.
Take things slowly. Everything you say makes massive sense and I do hope that you will still come to TP since you have a lot to offer others - me included.
All the best
