Wow. Just, Wow.
Mate, I can't begin to imagine, even after reading that, how you are holding together - i can only send my wishes and let you know my thoughts are with you.
I too am the same age, and reading about your life can completely relate to the position you were in a few months before this struck.
Keep being strong and utilize your support networks as much as you can, they will be there for you when you need the most.
And keep coming back here. The Dees are clearly doing something for you, and I'm sure you have the love and support from everyone on this forum.
All the best.
