Oh, my goodness, dear @SouthernBee.
You have so much to process, yet you are so calm, good-natured, and positive, clearly tackling each issue systematically and sensibly.
Something I learned when I was dealing with disabling anxiety and worry was to write down the problems, then list practical ideas for each one.
It helped me to be organized on paper and it also in the process organized my thoughts and calmed my anxiety.
Sounds like you're doing that same thing.
You're getting good information and your new clinic and doctor sound like the absolute best of the best.
There are state, local, and federal resources that might have options to assist you, and as @geezerette mentioned I wonder if there are online groups that might offer practical support.
My heart is with you, @SouthernBee!❤️
Few things reveal your intellect and your generosity of spirit—the parallel powers of your heart and mind—better than how you give feedback.~Maria Popova
