These are just words.
Yes, it is hard to come to terms with an altered lifestyle but you are wisely remembering the good as well as mourning what's lost. I am sure it is the same for all of us bereaved.

I've been comparatively quiet because I too have a huge jump in reality to accept and it's causing me a lot of anxiety.

I've done my bit by alerting our lovely young facilitator to free venues and she already knows we will all contribute food. I am hoping for the best.
