Songbird,
That is a unique and tragically beautiful loss. I am sure there is a physical ache where your guitar used to fit next to you.
But I think it is possible for some losses to be transformative. As an artist I really resonated with photography (the more remote locale the better) and did a lot of hiking and climbing to reach subjects. When this became impossible I found my need to create frustrated. What a lot of energy to hold onto! I ended up learning piano in the last few months, something I may not have done otherwise. Sitting still was never my forte.
I have discovered new abilities and found new things to love. With all that is available to try perhaps there is a hidden opportunity in the midst of the changes. I know nothing will quite replace your guitar and that is terribly sad but there are many ways for the soul to sing and I am sure that you will find one.
And for Mama, I am so glad to read of your improvements with treatment. You just may twirl again. Progress can be very slow but still come over time. I remember aching to dance (or even stand up) for the year I spent on a scooter thinking I would never do those things again. And yet just recently I did a little dance at home for my own enjoyment and I did alright.
Don't let go of any of those dreams just yet.
